I want to suppress the 'save and quit' option. Understand it is controlled by browser.showQuitWarning. Setting it to false would suppress the option for 1 time. Next time it is reset to true and the 'save and quit' appears again.

thanks for reply. have found out that I am using a linux distro who put a file at /usr/lib/firefox/browser/defaults/preferences/vendor-firefox.js changing the file fixed the problem.

Try go to Tools >> Options >> Tabs >> uncheck the option to alert when you will close Firefox, i think it is the second option.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

If you do not keep changes after a restart or otherwise have problems with preferences, see:
