When I started using Linux on my desktop there was only Mozilla based browsers which were usable. They had different names: Galeon, Firebird, Phoenix, Mozilla Suite and finally Firefox.
It worked better or worse but did. There were moments when on 2GB ram machine browser was using 6 gigabytes (which resulted in killing it). Then were moments when it started to be slower and slower so I moved to Google Chrome instead.
But still — Firefox had all those extensions which could do insane amount of things with how browser looks, how it works etc. But then Quantum came and changed that. Good bye all nice addons. Hope we meet in other life.
But what it has with question from post title? Simple, little, annoying thing: “Ctrl-Q” shortcut. Lovely one which everyone is using to close application they work with. Not that it does not work — it does. Perfectly. And this is a problem…
Imagine you have few browser windows opened. On different virtual desktops. With several tabs per window. Some open notes there, somewhere some not-finished wiki edit etc. Normal day. And then you want to close ‘funny kitten’ tab and instead you close all those windows/tabs, drop not finished notes/edits etc. Just because your finger slipped to “Ctrl-Q”.
For years most of users I know used one of those “disable ctrl-q shortcut” addons to NOT close all browser windows when your finger slips a bit when you wanted to close a tab (with “Ctrl-W”) or switch a tab (with “Ctrl-Tab”). Since Quantum it is not possible at all as there is no way how addon can alter shortcuts. Or how user can alter shortcut. No Way At All.
And then it appears that “Ctrl-Q” problem exists only under Linux. Under Microsoft Windows developers of Mozilla Firefox decided that “Ctrl-Shift-Q” will be a good workaround for the problem. Something similar under MacOS. But Linux still on “Ctrl-Q”.
There is a bug report opened for it but there were 4 major releases of Firefox without any change I highly doubt that anything will change in this regard.
Slowly thinking of making COPR repo where I would provide Mozilla Firefox builds with one patch: removing that “Ctrl-Q” shortcut…
Firefox 87+ has “browser.quitShortcut.disabled” option to get rid of shortcut from menu. And even without it used it now warns user after shortcut is used:
