</p><p>The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
<strong>Note</strong>: <em>This will cause you to lose any Extensions and some Preferences.</em>
</p>
<ul><li>Open websites will not be saved in Firefox versions lower than 25.
</li></ul>
<p>To Reset Firefox do the following:
</p>
<ol><li>Go to Firefox &gt; Help &gt; Troubleshooting Information.
</li><li>Click the "Reset Firefox" button.
</li><li>Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
</li><li>Firefox will open with all factory defaults applied.
</li></ol>

</p><p><b> To Enable SafeMode </b>
</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><p>If it works in Safe Mode and in normal mode with all extensions (Tools &gt; Add-ons &gt; Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
</p><p>Close and restart Firefox after each change via "Firefox &gt; Exit" (Windows: Firefox/File &gt; Exit; Mac: "Firefox &gt; Quit Firefox"; Linux: "Firefox/File &gt; Quit")
