Ever opened a lot of tabs in Firefox? Of stuff you wanted to refer to later, things you wanted to blog about, things you wanted to send to other people, and the like?
Ever noticed that your computer was running a bit slow as a result, and decide to reboot?
Ever relied on the useful "restore session" feature when Firefox crashes or you kill the process?
And ever close down Firefox by mistake rather than killing it from Project Manager, which then makes the "restore session" feature unavailable?
And ever have it slowly dawn on you that all that stuff that you wanted to do nifty things with is gone?
Yeah, me too.
(I try to tell myself that it's a clean slate and liberating and all that, but I think I'm still in a minor amount of shock.)
