When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

Hello, Could you please type about:config in the address bar

search for those two preferences and set them true: browser.sessionstore.warnOnQuit browser.warnOnQuit

Hope it will work out

Note that there is also a checkbox in "Options/Preferences -> General -> Startup" for the fist pref.

Firefox 87+ versions have a pref to disable Ctrl+Q to close Firefox. browser.quitShortcut.disabled = true You need to close and restart Firefox after toggling this pref.
