Gooreplacer empowers users by intercepting and modifying browser requests on the fly, giving you control over how websites load and behave.
Welcome everyone to share your Gooreplacer rules, help us all tackle those annoying internet roadblocks and enhance our browsing experience. 🚀
Add to browser
Gooreplacer is built with WebExtension APIs, so it supports a lot of browsers.
You can either install it from web stores or build from source code.
Why does Gooreplacer exists?
Gooreplacer was created for redirecting Google Ajax/Api/Themes to other CDN to bypass Great Firewall since pages referring those are slow as molasses.
The first commit dates back to September 16, 2014. Since then, I've rewritten the codebase several times to add features and enhance performance. The latest version (v4), released on April 26, 2025, achieves full compatibility with manifest v3.
User Guide
If you're only interested in redirecting Google resources, the following rules (which redirect to the loli.net mirror) will be sufficient:
||ajax.googleapis.com/,wildcard,redirect transform:host=ajax.loli.net ||fonts.googleapis.com/,wildcard,redirect transform:host=fonts.loli.net ||fonts.gstatic.com/,wildcard,redirect transform:host=gstatic.loli.net ||secure.gravatar.com/,wildcard,redirect transform:host=gravatar.loli.net ||www.google.com/recaptcha/,wildcard,redirect transform:host=recaptcha.net
