Firefox jumps!

[big-all]

i was on my asda yesterday and it was doing the mouse cha cha cha as well
just realised its because the thing about cookies at the top loads a split second later so as you go to click it jumps

Thanks.
I'll watch out for that next time it happens.

Having said that, I don't remember seeing the thing about cookies for a long time.
