Early this morning I noticed my Firefox becoming evermore sluggish. I went crazy removing add-ons to see which one could be the problem. None of them seem to have been the problem.
I looked into the FireFox folder:
Application Data\Mozilla\Firefox\Profiles\xxx.default
And there I saw 3,798 sessionstore.js files (numbered, of course). I deleted them and everything seems to be fine. I wonder what the hell happened?
