FoxyProxy Browser Extension

About (Changelog) | Help | Issues

After some years of stability, FoxyProxy has been updated to support Manifest Version 3 which is required by Chrome in order for extensions to be compatible with Chrome in 2024. We took advantage of this forced update to implement many feature requests and other changes that were requested over the years.

FoxyProxy has been owned and developed consistently by the same team since 2006.

The repository has the source code for version 8.0+ for Firefox, Chrome, and other Chromium-based browsers like Chromium, Brave and Edge.
Source code for older versions.
