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](https://github.com/Kaasplank1234/Search123/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.

Windows installation — Version 0.5.0

For Windows 10/11 x64 on Intel or AMD processors. This package is not a native Windows ARM64 build.

1. Download and install

  1. Download Browser123-0.5.0-Windows-x64-Setup.exe from this release’s Assets section.
  2. Close any running Browser123 windows.
  3. Run the installer and follow the instructions.
  4. Select Open Browser123 when installation finishes, or launch it from your desktop or Start menu.

The automatic Source code downloads are not installers.

The installer is not code-signed. Windows may display an unknown-publisher warning. Only continue if you trust and have verified the download. Do not disable antivirus or override a malware detection.

2. Enable the Browser123 homepage

  1. Enter chrome://extensions in the address bar.
  2. Find Browser123 by cheesy-studios and turn it on.
  3. Accept the new-tab change if prompted.
  4. Open a new tab with Ctrl + T.

Always start the browser using the Browser123 shortcut. Opening the internal Chromium executable directly skips the Browser123 launcher.

3. Check your Search123 search engine

Keep the separate Search123 — Address bar search extension enabled and approve its search-engine change if prompted.

To check the actual default:

  1. Enter chrome://settings/searchEngines.
  2. Confirm that Search123 is selected.
  3. If available, use ⋮ → Make default beside Search123.

If Search123 is missing, add it under Site search:

  • Name: Search123
  • Shortcut: search123.dpdns.org
  • URL with %s in place of query:
https://search123.dpdns.org/search?q=%s&category_general=1&language=auto&time_range=&safesearch=0&theme=simple

Save it and select Make default. Test a search from the address bar to confirm that results open on search123.dpdns.org.

4. Install your optional extensions

Use Install / manage on the Browser123 homepage to open the official store listings for:

  • Proton Pass — password manager.
  • uBlock Origin Lite — ad and tracker blocking.

These extensions are optional and are not bundled in the Windows installer. This Windows edition uses uBlock Origin Lite because the original Manifest V2 uBlock Origin is incompatible with its newer Chromium engine.

5. Customize Browser123

Open Settings on the Browser123 homepage to choose your color mode and accent color.

Click Save appearance. The homepage updates immediately; close all Browser123 windows and reopen it to apply the toolbar theme.

Windows troubleshooting

The homepage is missing: Check that the Browser123 extension is enabled, disable competing new-tab extensions, and reopen the browser using its shortcut.

Searches still use Google: Follow step 3. The homepage extension and address-bar search extension are separate.

Cloudflare verification keeps repeating: Temporarily disable content blockers for the affected website, allow JavaScript and required cookies, and reload. If necessary, test without a VPN or proxy and compare the website in an up-to-date mainstream browser.

Browser123 will not open: Confirm that your computer runs Windows 10/11 x64. If files are missing or quarantined, report the exact warning rather than disabling security protections.

Appearance settings will not save: Reinstall using the official installer to restore the settings helper, then try again.

Updating or uninstalling: Close Browser123 completely first. Uninstall through Windows Settings → Apps. Your browser profile is preserved.

Windows build limitations

This is an experimental test build based on a recent official Chromium snapshot. The installer and packaged files have been checked, but the browser has not been executed on Windows in the build environment. Cloudflare compatibility is not guaranteed.

There is no automatic Chromium engine updater. Some internal Chromium names and icons remain.

For support, open a [GitHub issue](https://github.com/Kaasplank1234/Search123/issues) with your Windows version, processor type, Browser123 version, and exact error message. Do not include passwords or private browsing data.
