Can you post a link to a publicly accessible page that doesn't require authentication (signing on) and also attach a screenshot? *http://en.wikipedia.org/wiki/Screenshot *https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem Use a compressed image type like PNG or JPG to save the screenshot. ----- Reset the page zoom on pages that cause problems. *<b>View > Zoom > Reset</b> (Ctrl+0 (zero); Command+0 on Mac) *http://kb.mozillazine.org/Zoom_text_of_web_pages Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled. *http://kb.mozillazine.org/about:config That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues. You can also try to uninstall Windows update KB2670838 if you have this update. *http://support.microsoft.com/kb/2670838
