    Closing my last tab kept closing the whole Firefox window, which drove me nuts. Someone said: type about:config in the address bar, accept teh "Proceed with Caution" warning, search for browser.tabs.closeWindowWithLastTab and set it to false... now closing the last tab just leaves a blank one.

    Then i started browsing around and realized about:config has thousands of preferences. Every option in teh nomral settings page is there too, plus many with no menu at all. Feels like i found teh engine room of my browser. thx in advance!!

    been there man about:support has a "Refresh Firefox" button if you break something badly. It resets settings and keeps bookmarks and passwords.

    yeahhh organizations can lock preferences with enterprise policies... if a value wont change, check about:policies. worked for me anyway 🤷
