Linux Mint Forums

Using Mint 14 Cinnamon fresh install/fresh ./home. Firefox's warning when closing multiple tabs won't turn off. I have unchecked Preferences>Tabs>Warn Me When Closing Multiple Tabs. I have also renamed ./mozilla and had the same result with new profile. I have also excluded all add-ons. Just switched from Ubuntu 12.10 which didn't exhibit this bug. Does anyone else have this behavior?

I got your back.

I've had this problem with just about every fresh install I've done of Linux Mint since Mint 12. Here's the solution. Open a browser window and type "about:config" in the address bar. Firefox will try to scare you away by telling you that messing around with these settings will void your warranty. Ignore it and soldier on (Warranty!? What warranty!?). You need to search for and change the following values:

browser.showQuitWarning this is set to "true." Right click and toggle it to "false"

browser.tabs.warnOnClose this is set to "true." Right click and toggle it to "false."

browswer.warnOnQuit this is set to "true." Right click and toggle it to "false."

Rest like a god!

Thank you! I would say you saved me from pulling my hair out, but I don't have any. The culprit was "browser.showQuitWarning". I had only searched about:config for "tab/close". This setting seems to be only in the Mint version of FF. I will file a bug report and point it to this post.

I created a bug report if you want to add some heat. https://bugs.launchpad.net/linuxmint/+bug/1082626

You jump started my brain. I tracked down the root of the problem, and posted the fix in the bug report. Hopefully this can be remedied in future releases.
