When the Firefox Safe Mode window appears, select "Start in Safe Mode".<br> [[Image:Safe Mode Fx 15 - Win]] To disable Hardware Acceleration * Click the menu button [[Image:New Fx Menu]] and select ''Options''. * 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.
