My tabs in Firefox have been VERY reliable for years. Whenever i shut down, or put the computer to sleep - the tabs were almost always there when i re-opened. Last night i closed my computer lid (ie, sleep, not shut down) and this morning, when I opened it all my tabs were gone and there is nothing available under my history menu to restore closed tabs or windows. I do have tabs from my other synced computer - but not from this. I also tried logging out and logging in - with no result. Is this is a dead duck or is there a chance to still restore my tens of tabs i had open? Thanks
