I just had my first Firefox crash where I lost all the tabs in my session (thanks to Firefox Panorama, that number was quite high too). Luckily, Firefox kept backups from the
sessionstore.js file, and the most recent was just 2 days old.
However it seems that the backups of those
sessionstore.js files is done quite rarely and I would like Firefox to backup it more often (like every second or every day, as it does with the bookmarks). Is there any way to do that?
