does not install

tl;dr: If you see "appears to be corrupt", search and install ZeroOmega, a fork of this extension. Be careful not to install some other malicious ones!!!

Some of you may see that "the add-on appears to be corrupt". It is because google has upgrade extension manifest v2 to v3 and this plugin is no longer maintained. There is a community fork of this plugin called ZeroOmega available on github: zero-peak/ZeroOmega. Someone upgraded it to v3 manifest so is able to be installed. Also, be aware that some SwitchyOmega copies contain malicious code and will inject unsafe code. Be careful with that!

I use this extension for years on Windows and Mac Chrome/FF and works great. I tried Ubuntu 24.04 today on FF and the error show that the extension is corrupt. Chrome works

very good

Proxy SwitchyOmega is a highly useful Firefox extension, especially for users who frequently need to switch between proxies. The interface is clean and easy to navigate, making it simple to configure and switch between different proxy settings without having to manually adjust the browser's network settings every time. Whether you're a developer, need to bypass restrictions, or often work in different network environments, this extension is a must-have. It supports various proxy protocols and runs smoothly—definitely worth recommending!
