hello kimahri1980, run a full scan of your system with the security software already in place and different tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes], [http://www.microsoft.com/security/scanner/default.aspx microsoft safety scanner] or [http://www.kaspersky.com/security-scan kaspersky security scan] since popups are usually a sign of malware active on the pc. afterwards reset firefox as described in [[Reset Firefox – easily fix most problems|this article]]. [[Troubleshoot Firefox issues caused by malware]]

Doesn't find anything, and it's not "Popups" as in new windows opening up, but new tabs.... Pops up no matter what I click on, try to "X" it, new tab opens, try to type something in to "Search", new tab opens, try to access Firefox Settings, new tab opens..... Only thing that has helped some what is installing "BlockSite" addon.
