Do you have that problem when running in the Firefox SafeMode? <br /> [http://support.mozilla.com/en-US/kb/Safe+Mode] <br /> ''Don't select anything right now, just use "Continue in SafeMode."'' If not, see this: <br /> [http://support.mozilla.com/en-US/kb/troubleshooting+extensions+and+themes]

Also do a malware check with a few malware scan programs.<br /> You need to use all programs because each detects different malware.<br /> Make sure that you update each program to get the latest version of the database before doing a scan. * http://www.malwarebytes.org/mbam.php - Malwarebytes' Anti-Malware * http://www.superantispyware.com/ - SuperAntispyware * http://www.safer-networking.org/en/index.html - Spybot Search & Destroy * http://www.lavasoft.com/products/ad_aware_free.php - Ad-Aware Free * http://www.microsoft.com/windows/products/winfamily/defender/default.mspx - Windows Defender: Home Page See also "Spyware on Windows": http://kb.mozillazine.org/Popups_not_blocked and [[Searches are redirected to another site]]
