Hello, Please can you try accessing some websites in Troubleshoot Mode to see if the icons are still created then. '''Try Firefox Troubleshoot Mode''' to see if the problem goes away. Firefox Troubleshoot Mode (previously known as ''Firefox Safe Mode'') is a special diagnostic mode that temporarily turns off hardware acceleration, disables add-ons (extensions and themes) and resets some settings. See the [[Diagnose Firefox issues using Troubleshoot Mode]] article for details. '''If Firefox is open,''' you can restart in Firefox Troubleshoot Mode from the Help menu: * Click the menu button [[Image:Fx57Menu]], click ''Help'', select ''Troubleshoot Mode'' and click ''Restart'' in the "Restart Firefox in Troubleshoot Mode?" dialog that opens. '''If Firefox is not running,''' you can start Firefox in Troubleshoot Mode as follows: * On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut. * On Mac: Hold the '''option''' key while starting Firefox. * On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox) When the Firefox Troubleshoot Mode window appears, select "Open". ;[[Image:Fx88TroubleshootMode]] ''To exit Firefox Troubleshoot Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again. (If you can't exit Firefox Troubleshoot Mode, please see [[Firefox is stuck in Troubleshoot Mode]]).'' Let us know what happens.
