Won't warn me when closing multiple tabs - even though it is selected in preferences.

When I close Firefox, it used to give me the option of saving my tabs. It doesn't do that anymore, even though I have that option selected under Preferences.

You can set the warn prefs on the about:config page to true via the right-click context menu or toggle with a double left-click.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.


You can use History > Restore Previous Session to get back the previous session.
There is also a "Restore Previous Session" button on the default about:home Home page. Another possibility is to use:

  • Firefox > Preferences > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"
