It was inevitable, the slimy bastards found a around having their popups blocked in Firefox. You become comfortable browsing without the popups, and then all of the sudden the world is tilted just a little. Here is a fix, for now:
To block pop-ups from plugins, open your Firefox 1.0 or 1.0.1 browser, type about:config in the address field. Right-click in the resulting config page somewhere and select New -> Interger.
Type privacy.popups.disable_from_plugins in the resulting dialog, hit OK, type 2 in the next dialog and you’re all set.
This pref can actually take three values:
* 0: open allowed
* 1: the opened windows are treated as popups, but they’re allowed to open (we limit the number of these types of popups)
* 2: the window is a popup, block it
