The page urls load properly but the pages generally don't show. I have been using Firefox 5 on Linux Mint 11. I have no idea which Firefox version I have on the Windows 7 PC as the Firefox "About Firefox" page doesn't display. Some web pages don't seem to be affected by the Firefox problem. As a workaround, I am using non-Firefox browsers like: on Linux- Konqueror, Opera, Seamonkey, Chrome; on Windows: Internet Explorer, Opera, Chrome; the iPod Safari and Android browser.
