What browser and Windows version are you using?
The only pop-ups I get are new configurations that circumvent the newest browsers.
I use an old IE 6 based browser for FR. It is one of the earliest tabbed browsers and it has some edit/add-ons that no longer exist for later versions. I also use FF5 and 7 for general surfing and seldom have a pop-up problem with those.
There may be come configuration settings you can adjust in your browser to stop those pop-ups.
F.R. is the only place where I get a pop up.
