Did you read the post? the OP is asking for options on how to change the KB shortcuts in Firefox and not what are the default KB shortcuts in Firefox.

Go to the Mozilla Add-ons Web Page {web Link} (There’s a lot of good stuff here) and search for what you want.

There were such add-ons per Quantum. I don't know if there are any now.

I installed the Saka key plugin but as far as I could tell there was no way to change the Ctrl+E hotkey, though many others were listed.

I did take a look earlier and one just now with a term I hadn't used before but didn't find anything that would help.

Hello bmcn99,

Would you give this a try :

Type in the address bar about:config and press Enter (promise to be careful, if asked)

Type in the search bar permissions.default.shortcuts

and (just to try) set its value to 2

0 = unknown action (default value) 1 = allow action 2 = deny action 3 = prompt action

If that doesn't do what you want, then change the value back to its default.

After you've changed a value, close and restart Firefox.

Note : changing the value will not affect only that one keyboard shortcut ......
