  • AC3/E-AC3 Audio support restored. It was disabled in the last couple of versions due to ffmpeg changes. Dolby Atmos audio is also restored. Note that for ARM/ARM64 builds, it is still disabled, due to incompatibilities with how Chromium loads the libffmpeg library.
  • WebRTC (used for real-time communication like video chats, i.e. Zoom, for example) can now use H.265/HEVC (recent upstream Chromium feature) on devices without hardware decoding support (Thorium feature). This is good because H.265 compression means that you will have less stuttery streams if you are on a bandwidth limited connection.
  • Fingerprinting protection patch added. Note this isn't a safety blanket, and doesn't mean Thorium will remove all types of fingerprint tracking it just makes it better than normal Chromium/Chrome. I would like to expand on this in the next version by adding a setting to enable the Global Privacy Control header, alongside the "Do Not Track" setting, which is also enabled by default in Thorium.
  • Added flag to enable/disable Side Panel Journeys, which can be annoying. chrome://flags#side-panel-journeys
  • Added flag to enable/disable showing the built in internal extensions that are normally hidden. They are now hidden by default (like in normal Chromium), but can be re-enabled with chrome://flags#show-component-extension-options. I did this because I was getting too many issues with people wondering what they are, why they couldn't be removed, and if they were a security concern. These extensions are built in to every Chromium browser. Disabling them would remove support for the Web Store, viewing PDFs, and integrating with Google Hangouts. I added a patch from UnGoogled Chromium a while back to un-hide them, but it has led to more confusion than it is worth. Since most people don't care, they are now hidden again, but the flag is for people who want to inspect or debug them, or just want the transparency of showing all extensions that are loaded in the browser.
  • The Side Panel Chrome Customization feature now works even if Chrome Refresh 2023 UI is disabled (Thorium has it disabled by default). However, fixing this this led to an unforeseen minor issue, that I didn't catch until everything was already built. Even if Chrome Refresh 2023 is enabled with the chrome://flags/#chrome-refresh-2023 and chrome://flags/#customize-chrome-side-panel flags as mentioned in the M123 release, it still won't actually work unless you also pass the --disable-features=CustomizeChromeSidePanelNoChromeRefresh2023 flag. Since I didn't catch this until afterward, there is no GUI flag available on the chrome://flags page. You will need to specify it manually on the commandline, either from the terminal, or to make it permanent, by editing the shortcut (on Windows), or editing /usr/bin/thorium-browser (on Linux). Next release will fix this.
  • The entire browser now respects Gamma/Alpha settings that the user has set for the display (Windows only for now). It is unknown how this will play with Thorium's JPEG-XL support. Feedback requested.
  • New commandline flag to disable the custom Thorium DNS config. Normally, Thorium uses two patches, to make DNS queries more privacy respecting, and to use DNS over HTTPS (DoH) by default, which is more secure and can't be intercepted by "man in the middle" attackers. However, this was breaking some people's configurations, especially when they had manually set DNS options in the OS, or were using external third party apps that change DNS settings (like VPN services). So, if you pass the --disable-thorium-dns-config flag on the commandline, Thorium will use the default Chromium DNS configuration. You can make it permanent using the same steps as above. I will also make this a GUI flag in the next release.
  • 32 Bit Linux is now supported, however I am not going to be regularly building binaries. But it is at least supported at the source code level again. There is an M123 release available. Note that Ubuntu 16.04 is not supported.
  • FTP support restored! Chromium and Firefox both removed all support for ftp:// URLs back in 2021. This has always annoyed me, because alot of ftp servers are still around, and alot of old software is only downloadable from ftp servers. In addition, tools like wget and curl wont download from them by default. This made it really convoluted to download files from an ftp website, usually making the user have to download a third party app. FTP means "File Transfer Protocol", and it was used heavily on the web for serving download directories to people (Microsoft used to host updates on an ftp site, for example). Learn more about it Here.
    It is enabled by default, but can also be disabled by the restored flag chrome://flags/#enable-ftp. There are two minor bugs though. First, favicons don't work, so when you are on an ftp site, the tab will show the "dino" icon usually used when a site is not reachable. Second, directly clicking links doesn't work, and will instead land you on an "about:blank#blocked" page. To go to an ftp site, right click the link, and select "Copy link address", and then open a new tab, paste the link in the address bar, and press enter. I hope to resolve these in the next version. This makes Thorium the only modern browser that supports FTP anymore. Thorium also now registers as an FTP URL handler with the OS, but I have not tested if opening an ftp url in an external app will cause Thorium to open it correctly, or land you on that "about:blank#blocked" page. Feedback is requested. Thanks to @win32ss for modernizing some of the code, since obviously stuff has changed alot in the Chromium repo since 2021. I took his patches, and adapted/fixed them to work on the M124 Chromium revision(s).
  • I enabled a feature that is normally disabled, that allows you to configure more options for PWA (Progressive Web App) windows. See the settings while in a PWA to see the extra options.
  • Global Media Controls (this little icon in the top bar > Screenshot from 2024-05-17 03-00-16) can be disabled again. I had enabled a feature that updates the UI on ChromiumOS/ThoriumOS, but it had the unforeseen effect of force-enabling it on other platforms.
  • Major vulnerability CVE-2024-4671 is fixed in this version.

M123.0.6312.133 - 39th Release

  • Enabled WebSQL by default (for things like Session Buddy 3)
  • More compiler optimizations in PGO (Linux-only for now) > Alex313031/thorium@acf69dd#diff-9b63dea0428a0efde7b9737c2b752678592868f64817cfbad4af4767d4bdfa84
  • More compiler optimizations (well, actually the removal of some LLVM flags) > Alex313031/thorium@c55c6b3
  • Disabled the ugly "Chrome Refresh 2023" UI by default Alex313031/thorium@ec8b741 however, if you decide you want it, set these two flags to true: chrome://flags/#chrome-refresh-2023 & chrome://flags/#customize-chrome-side-panel
  • If Chrome 2023 Refresh UI is enabled, then I added updated icons for the top bar (colored by default like usual, but can be made grey with the chrome://flags/#disable-thorium-icons flag). > Alex313031/thorium@ec8b741
  • Minor spacing and spelling fixes on some chrome:// pages that Thorium modifies. > Alex313031/thorium@8d050fc
  • Added Policy Templates for people wanting to set enterprise policies, or simply to see the available Windows Registry keys to control certain behaviors. These are identical to the ones for Chromium, except the directory names and registry key names have been changed to "Thorium" so that you don't have to do that yourself. They are in the file. > Alex313031/thorium@dcf4dd9
  • Added a Memorial easter egg dedicated to my Grandmother "Gramma Linda", who I spent the last month in the hospital with, and she sadly died March 23, 2024 at the age of 83. 😭 Born on Dec. 27th, 1940. You can view the easter egg by running Thorium from the cmdline with --enable-logging --v=1 >> C:\place\where\you\want\debug.log. The top of the logfile will print the Thorium brand name and version, and under that is my little memorial code. > Alex313031/thorium@8c0850e
  • The NTP page was broken when using a search engine other than Google, including the extra ones I added to some locales. I fixed it here > Alex313031/thorium@e113003
  • Fixed the disable-encryption flag not working properly (for users of the portable .zips) > Alex313031/thorium@1ac0e00 This should fix issues where Thorium signs you out of sites on every restart.
  • Updated libhighway in the libjxl repo to 1.1.0 > Alex313031/thorium-libjxl@1a4d1e7 for better SIMD optimization
  • Update libjxl to 0.10.2, which makes JPEG-XL rendering much faster, and fixes bugs when images were above a certain size > Alex313031/thorium-libjxl@fb2a3d6

Big news! On top of Thorium continuing to support Windows 7/8/8.1 (which I have been doing for a while now, since M110), Thorium now supports Windows XP and Windows Vista! I made a page dedicated to it, with an XP style theme similar to the Win7 page >

Download releases for all these Pre-Windows 10 OSes here >

This also means that Thorium now supports more OSes and architectures than ANY other browser on the market!. Windows XP - 11 x32, x64, and arm64. MacOS x64 and arm64. Linux x64 and Raspberry Pi arm64. And Android arm32, arm64, and x86.

Thanks to @gz83 for helping with Windows builds + policy templates, and @win32ss for providing the baseline patches used to restore Windows XP/Vista support.

M122.0.6261.132 - 38th Release

Nothing too special this release, just your standard Chromium upgrade.

However, five things:

  • Fixed the profile picker crash, which would cause Thorium to just segfault and crash without warning or any useful log output if you tried to add a new profile, OR if you had multiple profiles already added. This is my fault and I was being a dummy last release. Let me explain: Last release notes I said "Enabled AutoPlay toggle in Settings, I previously had it disabled due to a crash". Well I literally left myself a comment line to remind me what the crash was > Alex313031/thorium@5373a94#diff-67eea7cc5329808ed94c726a817ead2b1ac9a0d35a01e6360f553f7e63703572R1116 Yet I just tested to make sure the browser didn't crash on startup (which it wouldn't on my end because I only use one profile). I forgot to check by making a new profile(s). Thus, I declared the bug "fixed" when it really wasn't, and promptly got spammed with a bunch of sad people who's browsers were crashing. This was a stupid mistake on my part, and I'm sorry to anyone whos workflows got interrupted and the frustration that people were having. I will probably leave this setting disabled indefinitely, since I already added a chrome://flags flag to control this behavior anyway > chrome://flags/#autoplay-policy Fixes Alex313031/thorium#577, Alex313031/thorium#564, Alex313031/thorium#596, Alex313031/thorium#586, Alex313031/thorium#570, Alex313031/Thorium-MacOS#45, Alex313031/thorium#575, Alex313031/thorium#572, Alex313031/thorium#599, #176, #169, and Alex313031/Thorium-MacOS#42
  • Disabled some more "Privacy Sandbox" bullcrap
  • Added a patch from Ungoogled to disable captive portal detection. Note this won't work in all cases. Fixes Alex313031/thorium#528
  • This release is actually ahead of the version in official stable Chrome right now (.128 minor rev), as I spotted a nice security fix in V8 that was not landed until the .132 minor revision.
  • Thorium now installs the "dev" build of UBlock Origin (to better block YouTube ads)

Also, I got more issues regarding people disliking the custom colored top bar icons. Reminder that since M121, I added a flag to disable these > chrome://flags/#disable-thorium-icons

M121.0.6167.204 - 37th Release

20 Feb 05:47
Choose a tag to compare

M121 Thorium's 30th version birthday!

  • Disabled annoying feature promos like "Show me how to set Chrome's theme?" and "Do you want to take the privacy check now?". It wouldn't be so bad if these didn't appear randomly, and interrupt your workflow by blocking interaction with the rest of the browser until you click "Yes" or "Not right now". (Also notice how they say "Not right now" instead of "No". WTF is up with corporations doing this. It's subtle, but it's like psychologically saying "we'll let you say no now, but we expect you to change your decision later". Like no, leave me alone!).
  • Dolby Vision should now use proper color space info from your machine. Note that Dolby support still requires a hardware decoder to work at all, unlike HEVC/H.265 content which we added a patch to allow software decoding.
  • Updated libhighway to 1.0.7, and libjxl to 0.9.2. This should hopefully fix the JPEG-XL HDR issues some people reported. Should fix Alex313031/thorium-libjxl#18
  • On Windows, the mini_installer.exe unpacks itself faster due to an upstream change.
  • On Windows, preloading the browser, for example with background mode enabled, is now a little bit faster due to preloading pdh.dll and uxtheme.dll from system32.
  • Network Certificates now use the BoringSSL library (yes that's really its name), which is better overall than OpenSSL. (Don't worry, BoringSSL is still open source, and is actually a fork of OpenSSL).
  • Enabled a new Experimental feature, called kResponsiveToolbar. This makes it where when the window size is too small to hold both the tabstrip and top bar buttons (for example if you have alot of pinned extensions), the top bar buttons will be moved to a little chevron overflow menu.
  • Re-enabled a setting that I previously disabled due to crashes, which allows you to toggle AutoPlay settings at chrome://settings/content/sound
  • Added a much requested feature to be able to disable the colored custom top bar icons. You can now disable them with the flag > chrome://flags/#disable-thorium-icons. Rejoice! as I know many people don't like that I added blue and green colors to those. Note that icons used in the menus and settings still have blue colored triangles. I'm not gonna change those, as it's too much work and most people don't care about those. Fixes Alex313031/thorium#307 and Alex313031/thorium#66
  • Prevented Thorium complaining about missing Vulkan drivers on non-Intel platforms. This has been a long standing issue in Chromium, but I'm not going to file a bug because it is used by their infrastructure.
  • Added Thorium's extra search engines to even more locales, including Mexico and Venezuela.
  • Completely disabled the "Privacy Sandbox" (previously known as FLOC), because it's a s**tshow, and not good for user's privacy at all. See >
  • Enabled a compiler flag called _LIBCPP_HARDENING_MODE = _LIBCPP_HARDENING_MODE_FAST, which hardens C++ code against flow integrity issues and memory overflows, while still keeping stuff fast compared to = 1
  • Removed some extraneous LLVM opts
  • Re-enabled the chrome://whats-new page after I accidentally disabled it in M117.
  • More SIMD optimizations in the AVX2 versions.
  • I changed the download bubble flag name to chrome://flags/#disable-download-bubble, so if you changed this to restore the old download shelf, you will need to set it again.
  • Updated the documentation in the //docs directory, and on the site at which should allow you all to easily make your own builds now. Previously, following the docs which were very out of date (out of date for both upstream and because of the new build scripts added to the repo) would not yield a working browser. Fixes Alex313031/thorium#488, Alex313031/thorium#362, Alex313031/thorium#551, and Alex313031/thorium#477.
  • Added SSE3, AVX, and AVX2 builds for both Windows and Linux. I am deprecating the Thorium-Linux-AVX2, Thorium-SSE3, and Thorium-Win-AVX2 repos.

  • More optimization flags as per guidance from @RobRich999 here > RobRich999/Chromium_Clang#26 (comment)
  • Re-enabled component ffmpeg.dll (in case you ever wanted to replace it with a version that doesn't have proprietary codecs to make a "fully FOSS" build. Most people won't want this as it breaks media playback on alot of sites (including Widevine).
  • Added a new right-click menu item to "Save video frame" which you can use to save a .png of the current paused frame.

Added three new chrome://flags flags. These are:

  • chrome://flags/#vaapi-video-decode-linux-gl to toggle using the GL backend for VAAPI acceleration (Linux only). Fixes Alex313031/thorium#162
  • chrome://flags/#close-window-with-last-tab which allows you to keep the application open when closing the last tab (i.e. closing the last tab will simply open a new blank one). Fixes Alex313031/thorium#338
  • chrome://flags/#allow-insecure-downloads to fix the annoying issue where Thorium won't download files if they come from http:// ftp:// or "mixed origins" i.e. an http:// download initiated by an https:// page. Fixes Alex313031/thorium#509

IMPORTANT: Since we are building AVX2 and SSE3 releases every time now, I'm just gonna release them all here (Except the Windows on ARM versions). The Thorium-Win-AVX2 and Thorium-SSE3 repos will have an empty release redirecting users to this repo from now on. I will need to contact @ltguillaume in order to fix Thorium WinUpdater because of this.
Thanks again @gz83 for helping me make the builds.

M119.0.6045.214 - 35th Release

06 Jan 18:09
Choose a tag to compare

First, to address the easter egg and website stuff, here is my explanation/apology post > (it also addresses why I was gone for a month).

M119 (M118 was too old, so skipped that version)

  • Fixes multiple CVEs including GHSA-xm5p-7w7v-qqr5
  • Better HLS support
  • Better JavaScript compilation performance due to new Thorium compiler flags as well as upstream V8 re-workings.
  • Updated Widevine versions
  • The search engine choices that Thorium adds are now available in more locales. (Notably not in Russia or China because ya know, their governments not allowing certain URLs. Hong Kong and Ukraine are not affected).
  • Live Caption should now finally work (English only, sorry. The .grdp files for other languages are closed source for now).
  • ChromeCast can now use VP8 and VP9 codecs for less bandwidth consumption if you have slower internet. (Note that this is disabled by default in Chromium, I enabled it, but it is still experimental).
  • New chrome://flags flag chrome://flags#disable-aero This disables transparency effects and GPU accelerated window frame compositing (while still leaving GPU acceleration for the actual web contents intact). It is useful if you dislike transparency, or are getting glitches on Windows 11 with the window frame.
  • Storage Access API was disabled because the security risk is more than the usability improvement. If you need this, use the new chrome://flags/#storage-access-api flag I added to enable it.
  • Keyboard shortcuts in ThoriumOS now align better with Linux.
  • Portable version now also sets the cache dir to ./.config/cache, to prevent any disk writes outside of the dir.
  • Rejoice! If you are like me and hate the new "Download bubble" and want the old "Download shelf" back, well I reverted a commit from upstream, and now there is a flag for it! > chrome://flags#download-bubble
  • Windows builds are now more hardened against memory overflows by enabling the arg "win_enable_cfg_guards = true"
  • PGO is now more effective (thanks @RobRich999) > Alex313031/thorium@5fe3937
  • New flag from Ungoogled-Chromium chrome://flags#tab-hover-cards Allows removing tab hover card images, and instead replace with a tooltip (the behavior before M106).
  • Added SSE3 builds for people without AVX-capable CPUs

M117.0.5938.157 - 34th Release

10 Oct 12:48
Choose a tag to compare
  • Removed Linux middle click autoscroll by default because it caused bugs for some people. You can still enable it by using the cmdline flag --enable-blink-features=MiddleClickAutoscroll (and I removed the warning bar for people who do). Fixes > Alex313031/thorium#199
  • You can now choose to not show full URLs. Previously it was forced to true, and selecting/unselecting "Always show full URLs" would do nothing. It is now still enabled by default, but you can choose to unselect it. I will be making a PR to Ungoogled Chromium about this.
  • HEVC/H.265 decoding is now multi-threaded. Thanks to @RobRich999 for pointing this out and where to enable it.
  • Two major security vulnerabilities in libwebp and libvpx were fixed. See the new security policy for info about submitting security bugs, and a list of fixed vulnerabilities (which will be updated henceforth). If you use any of my Electron apps, those were also recently fixed.
  • On top of my Thorium-Win7 fork, which will soon be updated to be based on Supermium M118 (me and @gz83 are working on a unified patch for this), I also made a new repo: with ongoing work to resurrect Chromium on XP. I currently have fixed google search, compiling with the windows 10 sdk, and added Thorium's optimizations (minus AVX).
  • chrome_management_service should work properly now, if any of you out there are using Thorium with enterprise policies set.
  • Slightly higher Speedometer scores, due to both upstream optimizations, and me tweaking rustflags in the compiler config.

M116.0.5845.169 - 33rd Release

06 Sep 09:26
Choose a tag to compare


  • chrome://whats-new page has been re-enabled by me, after Google made it "Chrome only". You will see it launch in a new tab on every version upgrade.
  • I enabled an experimental setting in Appearance to toggle tab hover cards. This can also be controlled via the traditional chrome://flags flag
  • I enabled an upcoming UI design change that was supposed to land in M117, but I enabled it early. This moves the Extensions submenu from "More Tools" in the main menu, into its own dedicated menu item.
  • New "Name Window" item in "More Tools". This allows you to manually override the window name, i.e. what appears in the window's title and what appears in the taskbar.
  • initial_preferences file is now included in the Windows installer, to show the Welcome page on first launch after the first install.
  • New internal variable specifying the type (i.e. AVX, AVX2, SSE3, etc.) is being shipped to facilitate the new Thorium-Win-Updater project me and ltguillaume have been working on, to allow auto update for Windows (Linux users already have it, if you are using the deb repo).

Thanks @gz83 @ltguillaume for helping.

Also, on another note, people have been complaining about me not releasing a new version on the exact same day as a new major Chromium version. To those people, I say, every major version takes me about 6+ Hours of intensive work to rebase. This is followed by many more hours for both me and @gz83 and @midzer to build each version, and this is assuming we are using all of our CPU cores pegged at 100% usage, which also slows our machines to a crawl for if we want to do anything else. Please be patient. If people still make issues or discussions about this, my response will be going forward: Then you try maintaining a Chromium fork!

M115.0.5790.172 - 32nd Release

14 Aug 07:46
Choose a tag to compare

M115 : This release is all about bug fixes, rather than new features.

  • Storage Access API enabled by default upstream. I actually have a web app on the Thorium website that can make use of this new web standard >
  • Added Middle Click AutoScroll for Linux (normally only enabled on Windows). Please report any bugs encountered - Fixes Alex313031/thorium#199
  • REMOVED Wayland VAAPI patch as it was causing too many bugs for too many people to be worth it. - Fixes Alex313031/thorium#162
  • Tabstrip window dragging bug fix for Windows (and possibly Linux and Mac, pending further investigation). - Fixes Alex313031/thorium#197
  • Profile picker crash fix. This was a major bug that occurred on all platforms, causing the browser to crash when trying to select a different profile other than the default one or guest one. Fixes #58 and Alex313031/Thorium-Win-AVX2#95. The cause of it was narrowed down to this line, something completely unrelated code wise, but somehow caused a segmentation fault in the memory manager.
  • NTP Discovery fix for Android (Not so much a "fix" but just removing it so it doesn't look ugly). - Fixes Alex313031/Thorium-Special#16 (comment)
  • Fixed potential building problems on MacOS.

Might also fix other strange tabstrip bugs that people experienced in M114.

Next release we are planning to update libjxl and add a "Close tabs to the left" menu item.

31st Release - M114.0.5735.205

30 Jul 21:27
Choose a tag to compare
  • Minor revision update to fix security vulnerabilities, as an interim release until M115 which will come in 2 weeks.
  • Fixed minor WebUI images missing
    Otherwise, same release notes as the previous release.
