OK, you want someone to add something useful? I will.

Today on one of my computers (WinXP, Firefox 3.0) I have lot my whole session of opened tabs, due to the "New & Impoved FF Not-Warning-The-User-System when closing multiple tabs OR Warning him *only* if he/she have set up in TOOLS the option 'on next startup, show my home page or a blank page (do not save session automatically)'"!

How? Detailed explanation follows:

If you want Firefox 3.0 to warn you when closing multiple tabs, the only option for you is now to choose 'on next startup, show my home page or a blank page' in TOOLS. OK, I did so. After I have set up Firefox to show blank page on next start up, I now receive warning when closing my browser. Great! It asks me 'Save & Quit/Quit/Cancel'. Thus, I can prevent from accidentally closing my browser with lots of tabs open, and get somewhat similar behaviour as in FF 2.0. I then select 'Save and Quit' and have my session restored next time it opens.

Cool. What's the problem? Well, the problem is that in TOOLS I *cannot* set up 'Restore my tabs & windows from last time when I open Firefox' to be automatic, because if I do so, then no warning when closing by accident Firefox! Well, so I had 'Open a blank page' set up, and then on every close I should select 'Save & Quit'.

Then at some point, I had to download a file, and so the download manager opened. I completely forgot about it, and after a while had to restart Windows for some reason. So I tried to close Firefox 3.0 and saw the familiar message 'Do you want to close X number of tabs?: yes/no'. I selected "yes" (I am very used to this message from Firefox 2.0), and besides, I *thought* that, as usual, my session will be automatically restored the next time.

Well, *it wasn't*! Why? As you know, so I can get the warning that I am about to close Firefox (as in FF 2.0!) with lots of opened tabs open, I HAD TO DISABLE my automatic session restore! But then, because I had Download Manager opened somewhere, FF 3.0 did not ask me 'Do I want to save my session and quit/Just quit/or Cancel", but instead *warned* me that I am about to close several tabs! So, as I was used to do it in FF 2.0, I have closed the tabs and then realised that I can't restore my session - I had to disable automatic Session restore of because of the *new & improved* Firefox 3.0 behaviour!!

Well, that's it. My session was lost, trying to use Firefox in the 'new way'. You say it's better? Well, let users decide, please! If even 10% of the people using Firefox complain about data loss, and FF closing without warning, or closing with a warning, but *only* if the risk of losing the opened tabs is greater, then please, change the FF behaviour!!

I don't remember anyone complain about how Firefox prevented the user from closing by accident all of the tabs opened. And you could have your session restored automatically every time Firefox started! No worries, if you close your download manager or not, no worries 'Did I answer correct QUIT or QUIT+SAVE dialog last time I closed Firefox?' ...no worries at all. Only if you had several windows opened with lots of tabs in them, trouble could occur, but then, I was using Firefox *only* with one window open, and always opened new windows as new tabs, so I hadn't this problem.

Now I have!

Firefox behaves in a way I (and lots of other people!) don't expect or like. Or you run the risk of losing your session, but only then having a warning 'Quit/Don't quit" on accidental close, and even in not in all of the cases (as it proved this morning for me!), or you have your session automatically restored, but then you run the risk of closing your browser without any warning at all, with tens of opened tabs and real ability to loose forms in https!

You say this is better behaviour? More logical? Improved?

I say, for me it is not. If I would be the only one, OK. But I am not. So please:

Give us a workaround. Extension, which makes FF 3.0 behave like 2.0 in this area. Option in TOOLS -> OPTIONS. Anything. Even, tell us how can we edit the Firefox code so we can get the behaviour we expect!

Thanks for listening! :-)

And if we must file a new bug / enhancement request, we'll do it. Just make so FF can WARN us when CLOSING multiple tabs/windows, EVEN if Session is set to be automatically restored next time it is opened!

If we must buy you a beer for that, or file a new Super-Ultra-Polite-And-Detailed bug explanation, we will do it! :-)

Thanks for listening for my arguments, again! I have just lost a session and I wasn't warned and I cannot have my session be automatically restored on each startup. This makes me sad. And willing to go back to FF 2.0...
