This is not a support website, this is for filing bugs. http://support.mozilla.com/en-US/kb/Pop-up+blocker#Pop_ups_not_being_blocked It's actually quite normal, some popups can't be blocked without causing problems for regular websites, as it's difficult to see the difference between regular windows and the type you want to block.

Jo Hermans.....My pop-up blocker is checked enabled, and this problem never occurred in previous firefox versions, only the new beta...I don't know whether it's a support or bug problem, but someone should fix it.

Nothing changed in the popup blocker - it's the websites that have started to use them again. And most of them are pop-unders currently. Since a pop under is a type of popup that is most likely the kind that you don't want, there might be something to do here, without breaking any legitimate sites See bug 565104 and bug 502824 for more info.

when all else failed, I looked at malware//spyware problems....removed an reinstalled my malware program (STOPZILLA), and ran a new scan...found a virus and a worm...computer is now running perfectly (atleast until the next incident occurs).
