Firefox Community Forum

Hi there, I'd like the option to unbind default keybindings. Specifically, the Ctrl+W to close a tab binding. I reflexively hit ctrl+W when I want to delete a word in a text box (from emacs/shell/vim/etc) and this has resulted several times in me closing the tab I was on and losing the text I was writing. It would be useful to me to be able to disable this keybinding so that I don't continue having these accidents. More generally, I imagine that some users will find some keybindings annoying and want to disable or maybe remap them.

So this is half a feature request, and also half a support request if anyone has suggestions for workarounds in the meantime.

I'm on Linux and have been using Firefox since I switched over. The first thing I disabled was restoring tabs because I never need it/find it annoying. I noticed that every time I would restart my computer with Firefox open it would restore the session. I understand that this happens because Firefox sees it as a crash so I changed the following settings:

• browser.sessionstore.resume_from_crash from `true` to `false`
• browser.sessionstore.max_windows_undo from `5` to `0`
• browser.sessionstore.max_tabs_undo from `25` to `0`
• browser.sessionstore.max_resumed_crashes from `1` to `0`

I changed those according to this guide: https://kb.mozillazine.org/Session_Restore#Completely_disabling_session_store

Unfortunately any time I restart my computer with Firefox open it resumes my session. Is there any other way to turn this off? Theres no way all of these settings do nothing.

I also deleted the contents of sessionstore-backups in the profile folder but it just recreates the files after a while.

My goal is to be able to restart and shutdown with Firefox open and not have to worry about it restoring tabs.
