Ad Blocking FiltersetP 1.0 This is FiltersetP without the need for the AdBlock extension.

You can update your own to suit sites you visit; as I find and properly check new elements/source/href blocks, I will incorporate them after sufficient testing. If you try to eliminate every single ad, FiltersetP will be 3 miles long and/or you'll have false positives, folks. If you see an ad popping up, right click it and get its properties, or inspect the element in DOM Inspector and add it to your personal list. I have a self-imposed, non-paid responsibility to make sure people don't have false positives. I don't even a "donate" button on here. Paramount to me is that none of you lose valuable site information you WANT to view.

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 these free programs to scan for malware, which work with your existing antivirus software:

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• Anti-Rootkit Utility - TDSSKiller
• AdwCleaner (for more info, see this alternate AdwCleaner download page)
• Hitman Pro
• ESET Online Scanner

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Thanks for your help but I had already solved the issue when someone suggested I reset firefox to its original specifications - this worked.
