Hi, unfortunately the addon seems installed but doesn't show anywhere on my Firefox ... I would like to understand why it doesn't and how to fix that ...?
I don't know how to contact the creator of this addon anywhere else than here unfortunately.

HELP ???

Edit : Thanks for the answer, it works perfectly now.

This extension is a no-brainer. I used the shortcut ctrl+shift+t all the time already. But through this extension, I can just use my mouse. Great and simple!

nice!

Nearly useless. Doesn't let you choose which closed tab to undo, only does the most recent one. No option to customize icon colors. I haven't tested if the extension even works without browsing history saved and in private mode, but I wouldn't be surprised if that's an oversight too.

Addon's worked perfectly for months now. A must have.
