Firefox, you have let me down.....

[Canyarion]

FireFox has become very slow on my PC. When I open it, it sometimes takes 10 seconds before the window appears. And other programs are much faster in the same situation.

I also hate it when I hit the 'back' button (or backspace) and it doesn't show the part that I was reading before, but goes back to the top of the page. It happens pretty randomly I think.
