Most of the time it is when I am using Facebook and have more than one tab open. At the moment it's a waste of time having tabs as options because I can't use more than one at a time or else every single page comes up with this error... a web page is slowing down your browser Does anyone have any bright ideas on how to get it to stop - I have search the net and changed and tweaked a few settings but nothing has made any difference at all.
