I managed to get the "close all tabs" addon working, but none of the others which I have tried (the "restart" including). I have also tried the "bookmarks button" and the "menu button" addons, both are not working on my Firefox v.55.0.2.

The button simply does not appear in the selection menu, although the addon is installed without error. Creating a completely new profile with no other addon installed did not solve the issue neither.

Maybe there is a solution. Thanks for your great work in any case!

This broke in Firefox 55, and I am not trying to fix it since changes in Firefox 57 will make this extension impossible at this time. I am trying to get as many of my extensions upgraded as soon as I can. But some of them (this one included) don't work with the API that WebExtensions provide.
