I have Firefox installed on my desktop pc running windows xp professional. I had been using an older version but recently updated to the current version (4.01). Since then whenever I open up the firefox browser the page is all distorted The only way that i can really describe it is that it is sort of like a double exposure. I did do a print screen and then pasted it into a word document in hopes that I could attach it here but I don't see a place to add attachments. The actual address bar (for entering the website you want to go to can't be viewed (can click for new tab and start typing the address but you can't view it because of what is like a double exposure of the tabs at the top of the page). Even the firefox website has the same sort of visual affect to it. I have tried going to about:config and entering network.dns.disableIPv6;false and switching that to true (no change) I have also tried adding network.dns.disablePrefetch;true to the about:config with no luck either (even tried switching it to false). I have also checked the proxy settings (just in case) and compared them to IE (checked the MS guide to proxy settings as well). None of this helped with the browser itself. Even if I try right clicking and refreshing / reloading the page it does not help. As well as closing the browser entirely and then reopening it. But oddly enough it will sometimes (if I don't get frustrated and just switch to the Google Chrome browser) suddenly be working properly. I have also tried disabling NoScript which I also installed after updating to the newest version of Firefox but that didn't have any affect either. Yet like I said it will sometimes just suddenly start working properly. I also use thee same browser with the same settings, add-ons/extensions and plugins on my laptop which is running Vista Home premium and I have no problems there when I open up the firefox browser. Any assistance would be so VERY Much Appreciated.
