Session Restore
John,
I just "killed" a Firfox Portable RC3 session on purpose using the task manager.
When I started Firefox again it opened up all the tabs I had before. This is what this feature is supposed to do. But I wonder, might it not be a good idea to have this disabled by default in Firefox Portable to save "writes" to the flash drive. I know this is why disk cache and history are disabled. I assume that for Session Restore to work it must write the state of Firefox, all its windows and all its tabs to the drive so it can restore them. This, I assume happens over and over and over again.
