A browser extension to modify HTTP requests :-)


At first, Gooreplacer was created for redirecting Google Ajax/Api/Themes to other CDN to bypass Great Firewall since pages referring those are slow as molasses.

More features have been added since then, mainly:

  1. block/redirect URLs based on user-defined rules
  2. block/modify headers based on user-defined rules
  3. Test rules in sandbox
  4. i18n (English + 中文)
  5. Export/Import rules, sync between Firefox/Chrome/Edge...
  6. A new UI built with ClojureScript + Reagent ❤️

Most users prefer gooreplacer than other similar extensions(HTTPS Everywhere/Redirector) for ease-of-use. Why not give it a try?
