I’m not sure if other Firefox users experience this but every once in a while one or even all of my browser window(s) will suddenly close without warning and I have to recall which sites I had opened in all those tabs.

I read in The Yellow Darts about the Session Saver extension for Firefox.  This extension will supposedly open your Firefox
with all the sites that were up when it crashed. I haven’t used it yet so I’d appreciate any feedback you have regarding this extension. Just leave a note on the comments section.
