Does not work for me.

Its inability to be used in New Tab, regardless of who is at fault, makes this useless for my intended purposes.

Really kinda junky. The user interface is nearly unusable (having to scroll right to find Save button) and it doesn't even have an option to do what I want (keyboard shortcut to show/hide the Bookbarks toolbar under the address bar). No good.

There are no instructions on where to go or what to do after installing the addon. yeah there is the "(ctrl+shift+a) ->Shortkeys ->Options" but that does not lead to where it claims to. Someone mentioned a FAQ but I can't even find that. what a useless addon.

"Example CTRL+B" and the bookmark opens....

If you're not going to fix the garbage UX, at least put this at the top of the about page:

"ctrl+d" -> "Do Nothing (Disable browser shortcut)" -> Scroll right to view the save button -> Save -> Restart Firefox

Probably prevent some 1 star reviews.

None of the hotkeys I try to remap save, despite clicking the Add button. I often use my ctrl button, and WASD. Ctrl+w closes my tab, and I don't want it to. This addon didn't help that in any way.

Simply does not work for default shortcuts. I want to disable ctrl+w for a webpage that has a terminal emulator, and ctrl+w is one of the shortcuts I need to enter. I try to disable it through the extension, and it does not work even after restarting the whole browser. Does not do what is described.

This did not work at all. I got it in the hopes of nullifying the annoying F12/F11 keys, and it did not function at all.

Same as @Lethe. Waste of time.

Can't get it to work after reading instructions and FAQ and googling for an hour.

Doesn't work at all, what a shame

The only reason I installed this extension was in order to disable built-in Firefox shortcuts, which is a feature noted in several places. There is even a "Do Nothing" action to take for a shortcut key designed for this purpose. But it doesn't work; after a "Do Nothing" shortcut key is defined, the key still does its original built-in action. There are bug reports in Github for CTRL-J and CTRL-Q, I wanted to disable CTRL-W...but the answer is "that's not supported by the new Firefox API". Well then, maybe you should remove the feature!
