This app is incredibly useful, works for links opened within Firefox and external programs.

The only problem is it breaks any other add-ons that require a log-in, like the OneNote clipper or Black Menu for Google. I have to temporarily turn off this extension to log in, then switch it back on.

神奇的扩展 解决我多容器登陆的问题，感谢作者

Works with links that are opened by Thunderbird. You are amazing!
