Need to remap Cmd+Shift+N to open new private window. This can't do it.

Not work on short cut "ctrl+shift+c"

Does not work with ctrl+alt modifiers, basically useless

No matter what page I go to it says the toolbar icon is greyed out and can't be opened. Useless

Doesn't work

Useless, I expected to remove many of the current shortcuts set in Firefox ... it permits only ADD new ones.

Cannot over-write FF default keyboard shortcuts, so a pointless waste of time IMO.

i wanted this for the same reason i wanted custom key shortcuts on Firefox though to my disappointment it turns out most of the keys you assign commands to are already in use by the browser already totes not worth installing tbh.

Only downloaded this to remove the default ctrl+p print option, but even with a shortcut set to 'do nothing' it still opens a print window, aka pointless.

Pointless. I don't need an addon to ADD more shortcuts, I already have support for that in my OS and there are plenty of apps for keyboard shortcuts which can be introduced across your entire system or at specific app level, why have an addon for it. Useless.
What I DO NEED is to be able to undo the 1990's Firefox restrictions of builtin shortcuts so I can actually use my keyboard as it was designed for.

DOES WORK BUT ITS USLESS, 90% of function do not work, just scrolling and disabling shortcuts works sometimes

Doesn't work.

Does not work, does nothing.

Not able to get it to work

Addon is greyed out, I hardly found the Options, I set multiple shortcuts, saved it but nothing happens! They don't work.

Unfortunately, doesn't work on firefox 107 / macos

doesnt work

I wanted an easier shortcut for "Open a new tab (Ctr+T)" for example (Ctr+Q).

Unfortunately, this is not possible
