</p><p><strong>If Firefox is open,</strong> you can restart in Firefox Safe Mode from the Help menu:
</p>
<ul><li> Click the menu button <img class="wiki-image frameless" src="https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/gallery/images/2014-01-10-13-08-08-f52b8c.png" alt="New Fx Menu" title="">, click Help <img class="wiki-image frameless" src="https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/gallery/images/2014-01-10-13-10-08-eaa722.png" alt="Help-29" title=""> and select <em>Restart with Add-ons Disabled</em>.

<p><em><strong>If the issue is not present in Firefox Safe Mode</strong></em>, your problem is probably caused by an <strong>extension</strong>. Please follow the steps in 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 to find the cause.
</p><p><em>To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.</em>
