Browser extension to customize favicons based on URL and title regex matching
Target any webpages with its URL or title and change its favicon. This enables you to differentiate favicons shared across multiple websites or environments.
If your rule isn't working, make sure your pattern is correct with online tools like regex101.
The extension is available on all chromium based browser (Google Chrome, Microsoft Edge, Opera, Brave) from the chrome web store.
Firefox doesn't have any published version yet while this feature is not implemented. However, the extension can be built and works after manually allowing all the requested permissions inside about:addons > Env Specific Favicon > Permissions.
Source code is based on the vitesse-webext template with manifest v3.
You can easily download the default favicon of your browser :
- For chromium based browsers, the favicon can be retrieved at
chrome://favicon,edge://favicon, ... - For Mozilla Firefox, the favicon can be downloaded from the source code
Env Specific Favicon doesn't update manifest.json icons for performance reason. However, it can be easily implemented by downloading and modifying the source code. Partial support has been removed in this commit.
