IMHO it was the restart that "fixed" it. I experience this "getting slow" think to happen for a long time. After several days of run, firefox needs to be restarted. 1. it's taking too much RAM, 2. usually causing higher CPU load than after restart with same tabs and history open. BTW: same I have to do with gnome-shell, so maybe some graphics card driver is leaking.
Not to be too frank, but do you think I'm an idiot? Do you really think I would report serious, consistent, ongoing performance issues with an application without bothering to try restarting it first?

I restarted Firefox many times. I restarted gnome-shell. I restarted my machine. Nothing helped. Performance was poor immediately after the restart. There was no perceivable degradation over time -- it was extremely poor right from when it started up and stayed that way.
