When I visit any webpage with Firfex 4 it will continually refresh the page. I don't suspect it to be automatic reload as it happens with any page that I visit. As it loads it will get to "75%" and then reload automatically and repeat. To get the page to load completely I found this workaround: I enter the webpage address than quickly open another tab (ctrl+tab) and while waiting in the blank tab the page I want to open opens without multiple automatic reloads. However, if I don't do that then the page refreshes many times, sometimes it will load after the 5th reload other times it will continued rehreshing. Also this problem doesn't happen all the time but it is persistent enough. Any ideas?

Also this happened with the previous Firefox version (3.5) but rarely, this time it happens 1-2 times per day
