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.

Doesn't seem to work anymore. At least not for me and the instructions to fix it if you have the bug doesn't do anything either. Side note, the checkbox "Restore previous session" literally doesn't exist but I assume that it is the "Open previous windows and tabs" box instead (which was already unchecked for me).
Will of course update my score if it gets updated and fixed and/or I find out it's my fault it doesn't work.

Still doesn't actually work for me but seems to work for the other people that reviewed after me so it must be an issue on my side only.

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.

Icon colors are not clear under bright themes. Update and fix it please :D
