Reproducible: Always Steps to Reproduce: See above. Actual Results: Current Nightly is not saving tabs. Expected Results: I should be asked if I want to save the current session upon closing.

This is expected behaviour from bug 592822, if you want to restore your session you can make that decision at startup from the History, Restore Previous Session option. Additionally the about:home page is being changed to include a button to quickly restore the previous session, (bug 593421) If you want to revert to the old behaviour just toggle the pref browser.warnOnQuit to true. Resolve invalid?

Okay - got it. I have a suggestion, though, so you don't get invalid bugs. I download the new Nightly every day and it confuses the BLANK out of me when something was working yesterday, then it is "broken" today so I file a new bug. Then you tell me this is intended behavior because a bug was fixed and the patch applied. How about adding on the start page (nightly.mozilla.org) what bugs are actually applied in that build, so I know if something is indeed broken or not?

Although not a mozilla site the mozillazine forums have a daily thread that includes all the fixed bugs for that days nightly. The forum is at http://forums.mozillazine.org/viewforum.php?f=23 and each daily thread is titled "The Official Win32 <INSERT DATE HERE> Trunk build is out." The first message in that thread contains a green list of checked in bugs for that days nightly build.

This strikes me as an incredibly poor choice on the part of the developers. It removes a useful future (requiring an about:config hack to reinstate), and it leaves an option in the config dialog that no longer works - "Warn me when closing multiple tabs." Big thumbs down on intentionally making this part of Firefox harder to use.

I agree with you. I still don't know what the "Warn me when closing multiple tabs" option does now, as it still appears in the current Nightly. If you want to restore your previous session, you have to remember to go to the Minefield/Firefox Menu, select History, then Restore Previous Session. Mozilla is working on adding a "Restore Previous Session" button on the "about:home" page, which you can see preview screenshots at bug 627301 (marked as a "final+" blocker).

This behavior has changed again, and browser.warnOnQuit no longer fixes it. Now, warnOnQuit literally just warns on quit, and asks if I want to close the tabs. How do I tell Firefox to save my tabs for next time, so that I don't have to remember to manually open a previous session?

When you are all done with your tabs / windows, instead of closing each window one by one with the red X in the upper right corner (which will display the warnOnQuit dialog), go to the Minefield / Firefox menu in the upper left and select "Exit". This will tell Firefox to automatically save all windows / tabs. Then, when you go back into the program (as long as you have "about:home" set as your default page), select the "Restore Previous Session" button on the bottom. If you do NOT have "about:home" set as your home page (which is the default when installing Firefox), go to Minefield Menu ---> History ---> Restore Previous Session. I DO believe that "Restore Previous Session" should have a keyboard shortcut / toolbar button for people who don't have "about:home" set as the default page.

Chris - that's the point of this bug. Manually going to History->Restore Previous Session was NOT necessary before beta 11, and in beta 11, the "browser.warnOnQuit" hack brought back the old behavior (the prompt to save the session and automatically resume it next time). Now, in beta 12, that hack no longer works, and I don't see any way to automatically resume the session. Having to go up into the menus to do something that was handled automatically in prior versions of Firefox is a pain.
