Browse123 1.0 Browser powered by Search123 (Chromium)

Browser123 1.0 — Orbit Light

By cheesy-studios · Powered by Search123

Browser123 combines a custom interface, a guided introduction and a centrally managed startpage with Chromium-based browsing.

Available for Intel Macs, Apple Silicon Macs and Windows x64.

What’s new

• Reduced interface overhead: tab updates are grouped, unchanged lists are not redrawn, and hidden companion panels pause their refreshes.

• Lighter native themes: light, dark and system modes with five accent colors, without bitmap theme textures.

• Cached startup setup: appearance files are updated only when needed. The Mac launcher no longer starts AppleScript on every launch.

• The five-step English introduction and Browser123 startpage remain included.

In a simulated burst of 1,000 relevant tab events, version 0.9 made 1,000 tab-list queries; version 1.0 made one. This is an implementation test, not a real-device speed or memory benchmark.

Features

• Shared Browser123 startpage, managed centrally on start.me.

• Search123 address-bar search through a separate extension.

• Companion sidebar for switching and closing tabs, finding bookmarks and opening browser tools.

• Custom dashboard, appearance settings and a replayable introduction.

• Support for compatible Chrome extensions.

Mac: includes Proton Pass 1.43.0 and uBlock Origin 1.75.0.

Windows: provides official-store installation links for optional Proton Pass and uBlock Origin Lite. These extensions are not bundled in the Windows installer.

Downloads

Choose the matching file under Assets:

Device | File -- | -- Intel Mac · macOS 11+ | Browser123-1.0.0-macOS11-Intel.dmg Apple Silicon Mac · macOS 11+ | Browser123-1.0.0-macOS11-AppleSilicon.dmg Windows 10/11 · Intel/AMD x64 | Browser123-1.0.0-Windows-x64-Setup.exe

The automatic GitHub Source code downloads are not installers.

Installation

Mac: Quit the previous Browser123 completely with Command + Q. Open the matching DMG, drag Browser123 into Applications, and launch it from there. A guided installer is also available in Support.

The Mac app is not Apple-notarized. Only use macOS’s normal Open Anyway option if you trust the download.

Windows: Close Browser123, run the installer and follow its instructions. The installer is not code-signed, so Windows may display an unknown-publisher warning.

Never disable antivirus or override a malware detection to install this browser. Existing profile data is preserved, but back up important bookmarks and passwords before upgrading.

First launch

1. Enable Browser123 and Search123 — Address bar search at chrome://extensions if necessary.

2. Approve their new-tab and search changes when prompted.

3. Open a new tab to follow the introduction.

4. Pin Browser123 through the toolbar’s puzzle menu to access the companion sidebar.

5. After saving an appearance choice, fully close and reopen Browser123 to apply the native theme.

After completing or skipping the introduction, new tabs open the shared start.me page.

If searches still use Google

Open chrome://settings/searchEngines, find Search123, and select ⋮ → Make default.

If it is missing, add:

• Name: Search123

• Shortcut: search123.dpdns.org

• URL:

https://search123.dpdns.org/search?q=%s&category_general=1&language=auto&time_range=&safesearch=0&theme=simple

Save it, then select Make default.

The search box on start.me is configured separately by its page owner.

Troubleshooting

Still slow? Open More tools → Task manager to identify the page or extension using CPU or memory. Compare the same websites with one optional extension disabled at a time.

Homepage or sidebar missing? Check that the Browser123 extension is enabled and launch the browser through its normal application shortcut.

Cloudflare verification repeating? Temporarily disable content blocking for that website, allow required JavaScript and cookies, and compare in an up-to-date maintained browser. Cloudflare compatibility is not guaranteed.

Do not delete your browser profile as a troubleshooting shortcut.

Important limitations

This is an experimental release. Version 1.0 is not a guarantee of stability or that every slowdown has been resolved.

Package integrity and implementation checks have passed, but physical-device runtime, visual, performance and Cloudflare tests have not been completed.

• Mac: uses older Chromium 138.0.7204.0 for macOS 11 compatibility, without current engine security patches or automatic updates.

• Windows: uses Chromium 159.0.8130.0 development snapshot r1729109, without an automatic engine updater.

• Bundled Mac extensions are not automatically updated.

• Native tab shapes, the address bar and menus remain Chromium. Some internal names, icons and technical credits also retain Chromium branding.

Prefer a maintained, up-to-date browser for sensitive accounts.

Source and licenses

Original Browser123 source and license notices are included in Support. The separate Browser123-1.0.0-Source-and-checks.zip contains original code and implementation tests.

Third-party components retain their respective licenses and copyright notices.

• Chromium source

• Proton Pass 1.43.0 corresponding source

• uBlock Origin source is included in the Mac Support folder.

Report a problem

Open a GitHub issue with your operating system, processor type, Browser123 version and steps to reproduce the problem.

Browse123 Browser powered by Search123 (Chromium)

Browser123 by cheesy-studios

Powered by Search123 · Version 0.5.0 · macOS 11+

Meet Browser123, an experimental Chromium-based browser with its own English interface, a custom homepage, bookmarks, tabs, downloads, light and dark modes, and five accent colors. Proton Pass and uBlock Origin are bundled, alongside support for compatible Chrome extensions.

1. Download the correct version

Open Apple menu → About This Mac to check your Mac:

• Apple M-series chip: download Browser123-0.5.0-macOS11-AppleSilicon.dmg.

• Intel processor: download Browser123-0.5.0-macOS11-Intel.dmg.

Download the .dmg from the Assets section below. The automatic “Source code” downloads are not installers.

2. Install Browser123

1. If an older Browser123 is running, quit it completely with Command + Q.

2. Open the downloaded .dmg.

3. Drag Browser123 into Applications.

4. Open Browser123 from Finder → Applications.

5. Eject the disk image after installation.

3. If macOS prevents the app from opening

Browser123 is not Apple-notarized. Only continue if you trust the download.

1. Open Finder → Applications.

2. Right-click Browser123 and select Open.

3. If the warning offers an Open button, click it.

If that option is unavailable:

1. Try opening Browser123 once, then dismiss the warning.

2. Open System Settings → Privacy & Security.

3. Find the message about Browser123 and click Open Anyway.

4. Authenticate and confirm if requested.

On macOS 11 or 12, use System Preferences → Security & Privacy → General instead.

If macOS reports malware, says the app will damage your computer, or says it is damaged, stop and report the exact message. Do not disable macOS security protections.

4. Enable the Browser123 homepage

If a new tab shows the standard Chromium page:

1. Enter chrome://extensions in the address bar.

2. Find the Browser123 homepage/dashboard extension.

3. Turn its switch on.

4. If prompted to approve its new-tab changes, accept them.

5. Open a new tab with Command + T.

If another extension controls your new-tab page, disable that extension and try again. You can also check here that Proton Pass and uBlock Origin are enabled.

5. Set Search123 as the default search engine

Version 0.5.0 may initially use Google. Check your default manually:

1. Enter chrome://settings/searchEngines in the address bar.

2. Find Search123.

3. Click its ⋮ menu and select Make default.

If Search123 is missing, click Add under Site search and enter:

Field | Value -- | -- Name | Search123 Shortcut | search123.dpdns.org URL with %s in place of query | See below

https://search123.dpdns.org/search?q=%s&category_general=1&language=auto&time_range=&safesearch=0&theme=simple

Save it, then select ⋮ → Make default next to Search123.

Search for a word from the address bar to confirm that results open on search123.dpdns.org.

More help: Search123 setup guide.

Troubleshooting

The homepage is missing

Follow step 4 and confirm that the Browser123 extension is enabled. Quit with Command + Q, reopen Browser123, and open a new tab.

Searches still use Google

Repeat step 5. Enabling the homepage extension does not necessarily change the address-bar search engine.

If the setting is locked or controlled by an extension, note the message shown in Settings and include it in your bug report.

Cloudflare verification keeps repeating

1. Temporarily turn off uBlock Origin for the affected website, then reload.

2. Confirm that JavaScript and cookies are allowed for that website.

3. Temporarily disable other privacy or script-blocking extensions.

4. If using a VPN or proxy, disconnect it and retry.

5. Compare the same website in an up-to-date mainstream browser.

Browser123 uses an older Chromium engine, so some verification systems and websites may not work correctly. Passing Cloudflare checks is not guaranteed.

Browser123 will not launch or closes immediately

Confirm that you downloaded the correct processor version, installed it in Applications, and completely quit the previous version before replacing it.

If the problem continues, report your macOS version, processor type, Browser123 version, and the exact error message.

An extension will not install

Some extensions require a newer Chromium version or features unavailable in this build. Compatibility with every Chrome extension is not guaranteed.

Known limitations

This is an experimental release, not tested on a physical Mac. It is built for macOS 11 and later, but compatibility across all supported Macs has not been verified.

The included Chromium engine has no current security updates or automatic updater. Avoid using this build for sensitive accounts.

Licenses and source code

Browser123 includes third-party software that retains its own licenses and copyright notices. Browser123-specific source code and license information are included in the Support folder.

Chromium source code

Report a problem

Open an issue on GitHub Issues. Include your macOS version, processor type, Browser123 version, steps to reproduce the problem, and any error messages. Do not include passwords or other private information.
