Hi, this worked well for me (Firefox 107 on Linux). I needed to disable the "/" shortcut key as was causing an issue when I was typing into a remote Citrix session in Firefox. Thanks for your work on this! :)

Does what it says, nice and easy to set up your own custom shortcuts and works great. Would recommend

Just came to Firefox from Chrome (have been wanting to for a while) and glad to see this extension here as well. Lightweight and works always as expected! Thank you

Did exactly what I needed it to do: Ctrl+I is used to invoke italics in many online email and text editors, but Firefox inexplicably has that key combination set to open Page Info.

It did what I wanted most, to use Alt+Enter to open Full Screen, though I can't toggle Full Screen with the same combination...
Also, it would be a good idea to instruct somewhere how one can choose a bookmarklet to assign to a shortcut; I am not sure clicking

nice little tool to customize Firefox
With this add-on, I can use the usual 'back' key assignment again :)

Only thing that works

It's dead - I wanted to match the shortcut for the sidebar to my 'normal' system sidebar shortcut, but I can't.

A little cumbersome to set up (e.g. I forgot to press the "Save shortcuts" button and thought it wasn't working), but after it's configured, it works perfectly! I finally was able to disable Firefox's bookmarks sidebar shortcut (Ctrl+B) which I activate by mistake all the time when trying to paste something (Ctrl+V).

It definitely works on Firefox 90 (the latest). Make sure you go to the GitHub page (linked in the add-on's description) and click the "Wiki" tab near the top to make sure you're setting it up right.
