Automatic session saving each 15 Minute

[Zumfra]

Hey guys, I use to browse the net on several Tabs simul

Hi, I usually have several tabs open at once—email, media sites, and so on.
Sometimes I have five or six open simultaneously, plus the one I’m actively browsing
 in.
Occasionally, a link opens in a new window; if I don’t close it right away, 
I forget it’s still running in the background. Then, when I close Firefox, 
I lose those five tabs because Firefox only saves the last window used.
If I click on "Recently Closed Tabs," Firefox might try to open a hundred tabs 
all at one time.
So, if my session were saved every 15 minutes, I could go back to the window I 
had before the mishap!
