Isnt support for FIrefox limited though? What I mean by that is that IE has widespread support. All web pages are tested in IE first. Mozilla, Firefox, etc are adapted later on.
I dont wnat to move to an inferior web browser.
Also, I havent opened too many windows yet (I only rebooted yesterday and normally the problem I have kicks in after 2-3 weeks or so), but as yet I havent come across the problem (after changing the page file to system managed).
