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.

To people who are saying this doesn't work: once you are on the 'Manage Your Extensions' page, you just need to click the little gear button near the top, and then click 'manage extension shortcuts' at the bottom of the pop-up menu. The description should perhaps be updated, but the add-on works. Make sure what you want is on the list though; and this add-on can't override existing shortcuts.
