When I have two browser windows open, the first with multiple tabs the second a window opened from a link (so just one tab), and close the second window, I receive the Quit Firefox prompt, "do you want to save tabs...?"

This was happening with FF 3 before upgrading to 4, and was not happening with FF4.0 until the 4.0.1 update was applied, the first time it ran. Same issue on another computer running FF3, so may be a extension related problem.

If I have three windows open and close the third, I do Not get this. Only when two are opened and one is closed. I could have three, close one, then the second and get the prompt.

Chosen solution

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Does that 2nd window have a Close Window hyperlink on that page and you are using the X in the upper right corner of that 2nd window to close it?

Use Firefox or File Exit to close all open windows at once if you want to restore the currently open windows.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session.
You can use "Firefox > History > Restore Previous Session" to get the previous session.
There is also a "Restore Previous Session" button on the default about:home Home page.

Another possibility is to use:

No, there aren't any close window links. I am closing with the X in the corner.

Usually I'll have some website open and just open a link to another website to read a page, look at a picture, whatever, manually. My main window isn't opening new windows as part of a website, it's just me right clicking and choosing Open in New Window on links that I'm bringing (the new page) front and center to read right then instead of queuing like I am with the first window.

Thanks for the follow up!

I'm not having a problem with restoring sessions. I'm having a problem with Firefox wanting to close when I close one window.


Also, I forgot to mention that the prompt comes up twice. So I click Cancel or the X on the 'Quit Firefox' prompt and it appears a second time.

Running in Safe Mode does prevent the problem. So it's looking like disable all addons, enable one at a time until it happens again/vice versa. Thanks!

I disabled one addon at a time, and actually found it on my second try. The problem was the HTML5 Extension for Windows Media Player, a extension actually created and provided by Microsoft if I remember correctly. With it disabled, the problem no longer occurs.

Thank you everyone for your assistance. I would mark cor-el's more recent post as the solution but am currently getting 'Access Denied' when I click the button.
