Bug Description
When I start firefox from cold it loads my tabs and all seems fine for a bit, then shortly after the window goes dark, it's unusable. I run iotop and discover firefox is reading about 1.2MB/s for about 5 minutes. I have to wait until this has finished, and can then continue to use it. The amount of IO seems to block everything else. For example just taking a screenshot worked, but then saving it took a long time (15 seconds) whilst the disk (SSD) was massively busy.
