--- Comment #13 from Josef 'Jeff' Sipek <jef...@josefsipek.net> --- I just had to restart firefox because it ate all the swap & RAM on the system. So, fission.autostart=false doesn't fix it/work around it. I don't know how much memory & swap firefox was using last night but I did *not* notice any memory-related lag when I went to bed. This morning (9 hours later), everything was very laggy - so I checked memory usage and found the system with 90-something percent memory and swap used. So, it isn't direct activity that causes this but rather something in the background. -- You are receiving this mail because: You are the assignee for the bug.
