What is Windows XP? please post a full system spec

Hi reggajt, Sorry to hear you have the issue ! Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches. You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.). Then perform these steps: #Open Firefox ''Options'' window (''Preferences'' on Mac or Linux) as follows: #* Click the menu button [[Image:New Fx Menu]] and select ''Options'' for Windows or ''Preferences'' on Mac or Linux. #In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''. #In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox. #Now, restart Firefox and see if the problems persist. Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles: * [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] * [[Upgrade your graphics drivers to use hardware acceleration and WebGL]] You can also start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes). Don't click the Reset button on the Safe mode start window or otherwise make changes. https://support.mozilla.org/kb/Safe+Mode Hope this helps!
