is not working, it says addon is corrupt, and has not been updated in 9 years?

Can't install :(

Used to work great, but after an update of either Firefox or the extension, it won't even install because the extension is "corrupt" or something. This used to be the only extension that would let you rebind the Tab key.

Doens't work :(

I want to disable ALT F,X which I often hit by mistake instead of ALT F,C.
However, it is impossible to disable even ALT F !
This extension has been ABANDONED for 5 years, so it's not surprising that it doesn't work.

why doesn't this work

[
{
"key": "Ctrl+Shift+N",
"label": "New Private Window",
"action": "newprivatewindow",
"sites": "",
"sitesArray": [
""
],
"activeInInputs": true,
"blacklist": false
},
{
"sites": "",
"sitesArray": [
""
]
}
]

Was hoping to be able to remap private window from ctrl+shift+p to ctrl+shift+n but it doesn't work.

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
