Hi, try this: Type '''about:config''' into the address bar, press Enter, accept the warning, scroll down to '''browser.newtab.url''' and make sure 'Value' is set to '''about:newtab''' (right click to change it). (Take care not to change anything else). I hope that will work for you.

Hi Shreyas11, Sorry you are having problems, but probably some adware or malware. Thanks for including System Information. I am not familiar with "PriceFountain" or "Roll Around" what are those ? Did you deliberately install the extensions ? * See http://malwaretips.com/blogs/price-fountain-removal/ * http://malwarebomb.com/roll-around/ Using the Firefox addons manager and the Windows Control Panel remove any obvious unwanted toolbars or programs. Then scan with multiple and fully up to date tools. *''' General method: [[Remove a toolbar that has taken over your Firefox search or home page]] ''' Please follow the advice in the link immediately above and then do the full scans as mentioned lower down in this post. I note you have a ''user.js'' file that may need attention separately. Post back saying what you tried and what the results were. -------- You can try these free programs to scan for malware, which work with your existing antivirus software: * [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner] * [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware] * [http://support.kaspersky.com/viruses/disinfection/5350 Anti-Rootkit Utility - TDSSKiller] * [http://general-changelog-team.fr/en/downloads/viewdownload/20-outils-de-xplode/2-adwcleaner AdwCleaner] (for more info, see this [http://www.bleepingcomputer.com/download/adwcleaner/ alternate AdwCleaner download page]) * [http://www.surfright.nl/en/hitmanpro/ Hitman Pro] * [http://www.eset.com/us/online-scanner/ ESET Online Scanner] [http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one. Windows 8 has antivirus [http://www.microsoft.com/security/pc-security/windows8.aspx#antivirus built-in] already. Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article.

You may have had an extension like Fast Start that has left this setting for the new tab page. *https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes You can use the SearchReset extension to reset some preferences to the default values. *https://addons.mozilla.org/firefox/addon/searchreset/ Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
