Please make sure you have the latest version of Adobe Flash and that add-ons are also not having an impact on this.
</p><p>Please check if all your plugins are up-to-date. To do this, go to the <a href="http://mozilla.com/plugincheck" rel="nofollow">Mozilla Plugin Check site</a>.
</p><p>Once you're there, the site will check if all your plugins have the latest versions.
If you see plugins in the list that have a yellow <em>Update</em> button or a red <em>Update now</em> button, please update these immediately.
</p><p>To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

<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> 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> 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><em>Once you get the pop-up, just select "'Start in Safe Mode"</em>
</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>
