in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

FF 84.0.1 Arch Linux

It appears that all 4 config. options mentioned in OP has to be set to true. In my case the one that was false was: browser.sessionstore.warnOnQuit Developers should fix this and let this option be true by default.

There is a checkbox in "Options/Preferences -> General -> Startup" for the browser.sessionstore.warnOnQuit pref.

  • Warn you when quitting the browser

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.
