How to remove browser extensions with eclean

Browser Extensions helps you find extensions installed across supported browsers and profiles, then remove the ones you no longer want. This is especially useful when you have several browser profiles and are not sure where an extension is installed.

How to remove browser extensions

1. Open Browser Extensions: Go to Uninstaller > Browser Extensions.
2. Refresh discovery: Click Refresh or use the retry action if eclean needs to scan browsers and profiles again.
3. Expand the browser: Open the browser section you want to review.
4. Expand the profile: Choose the profile that contains the extension.
5. Review the extension: Check the extension name and profile before removing it.
6. Uninstall the extension: Click Uninstall and confirm if eclean asks.
7. Restart the browser if needed: Close and reopen the browser if the extension still appears until the browser refreshes its profile data.

If an extension will not uninstall

• The browser may still be running and holding profile files open.
• The extension may be managed by a browser policy, work account, school account, or security tool.
• You may be looking at a different browser profile than the one currently open in the browser.

Technical deep dive

Browser Extensions currently supports Chromium-family profile layouts and Firefox profile layouts. The built-in browser definitions include Google Chrome, Mozilla Firefox, Microsoft Edge, and Brave Browser, and eclean can also detect compatible profile paths in common browser locations.

For Chromium profiles, eclean scans the Extensions directory, reads the latest version directory for each extension, parses manifest.json, resolves localized name and description strings, extracts icon data when possible, and reads enabled state from the profile Preferences file. Uninstalling a Chromium extension removes the extension entry from Preferences and Secure Preferences, then deletes the extension directory.

For Firefox profiles, eclean scans the extensions directory and supports both .xpi files and unpacked extension directories. It reads enabled state from extensions.json when available. Uninstalling a Firefox extension removes the matching directory or .xpi file.

Firefox extension toggling is not supported through eclean in the current implementation. If you need to enable or disable a Firefox extension without removing it, use Firefox's Add-ons Manager.
