'''Scan for malware''' Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of. You can try some of the following programs to scan for malware: * [http://www.malwarebytes.org/mbam.php MalwareBytes' Anti-Malware] * [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility] * [http://windows.microsoft.com/MSE Microsoft Security Essentials] (A good permanent anti-virus if you don't already have one) Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article. '''Reset Firefox''' The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.'' To Reset Firefox do the following: #Go to Firefox > Help > Troubleshooting Information. #Click the "Reset Firefox" button. #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish. #Firefox will open with all factory defaults applied.
