</p><p><strong>Try Firefox Safe Mode</strong> to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
</p><p><em>(If you're not using it, switch to the Default theme.)</em>
</p>
<ul><li> On Windows you can open Firefox 4.0+ in Safe Mode by holding the <strong>Shift</strong> key when you open the Firefox desktop or Start menu shortcut.
</li><li> On Mac you can open Firefox 4.0+ in Safe Mode by holding the <strong>option</strong> key while starting Firefox.
</li><li> On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
</li><li> Or open the Help menu and click on the <strong>Restart with Add-ons Disabled...</strong> menu item while Firefox is running.
</li></ul>

</p><p><em><strong>If the issue is not present in Firefox Safe Mode</strong></em>, your problem is probably caused by an extension, and you need to figure out which one. Please follow the <a href="/en-US/kb/troubleshoot-extensions-themes-to-fix-problems" rel="nofollow">Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems</a> article for that.
</p><p><em>To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.</em>
</p><p><em>When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.</em>
</p><p>Thank you.
