A feature which I often use in Firefox is the Save & Quit feature which you’ll get when you’re prompted with the message “Do you want Firefox to save your tabs for the next time it starts?“. This is very handy if you need to close Firefox, for whatever reason, and you want to save the tabs which you have open at that moment. By doing this the tabs will be saved and will be re-opened the next time you launch Firefox again. This is feature which was build-in for a long time and was enabled by default. Unfortunately not anymore!
Ever since the update to Firefox 4 I kinda missed this option and it seems that the Mozilla team has decided to disable this feature from now on. Don’t ask me why cause I don’t see why this should be disabled. However there is a way to enable this feature again.
- type about:config in the address bar
- Promise Firefox you’ll be careful…
- Find browser.showQuitWarning by filtering it in the filter bar.
- Once you found it, double-click on it and set its value on true
- That’s it!

Save & Quit option
By doing this you’ll get this feature back without the need to restart Firefox 4. Now you can Save & Quit when you want to close multiple tabs. This is much better then to be prompted with “You are about to close X tabs. Are you sure you want to continue?” message, right?

haven’t fixed my FF4 yet..

Cool!! Gonna check it now!
Thanks for the share. Here’s what i did on my computer.
Step 1 – Type ‘about:config’ into the address bar
Step 2 – Search for ‘browser.showQuitWarning’ under filter
Step 3 – Right click the value and select ‘Toggle’
Step 4 – The value will change from ‘false’ to ‘true’
This is the same steps as explained in my post… So I assume that this worked?
Its good that you explained this method.. Actually, I am having a weird problem that the Firefox 4 keeps crashing and it doe snot come back to normal.. All the data of the previous session is lost..
First make a backup of your bookmarks etc and then un-install FF4 and re-install t again.. Perhaps there’s something wrong with one of the files?
I have a similar problem with Rohit Sane. It’s always crashing. I’ve reinstalled it but it is still crashing. I consider to switch to IE 9.
You must be kidding me!
IE9? I have seen a lot of website which doesn’t show properly in IE9!
I’ve tried this a bunch of times on my Firefox 10 but it doesn’t affect it at all. Any ideas?
