I used to be able to use Firefox to browse sites like http://www.sportsradio610.com and http://vip.wordpress.com without issue; however presently Firefox is displaying the pages as white background only, seemingly without frames, and "not correct". For example - on the sportsradio610 site, i only see only a single frame that runs top to bottom. The "Home", "On Air", "Pics" etc that are supposed to be part of the scroll-over navigation bar instead appear as basic hypertext links in blue lined up on the left hand margin. The "Listen Live" link, which is supposed to appear in the top of the right-hand frame instead appears almost at the very bottom of the page. On the vip.wordpress.com site - again a white background, all the hypertext links are in old-school HTTP blue only, and the icons for "Video", "CNN", "flickr" etc are all stacked up along the left hand margin; the icons appear as transparent, block letters. The paragraph "A successful blog presents..." appears below the Flash video (Flash video doesn't play either) instead of where its supposed to be (to the left of the flash video, which is supposed to work properly also). Both of these websites display correctly on this machine with IE - and on other machines with both Firefox & IE. I've already re-installed Java, Flash, Firefox updates and Microsoft Windows updates, as well as checked the Firefox plug-ins... Seems to be a problem confined to this machine's Firefox install. I can't duplicate it on another machine.
