It is obvious that the ads are being served by other HTTP servers. However, my Firefox settings are to block such popups, and these particular scammers have devised a new way to force the popups to appear regardless of my settings. I can't really say how often they succeed, but not very often. I haven't managed to find the relevant source on any page that seems to be the cause of the popup, so I guess hiding the source is part of the trick.
I can confirm that I've seen it on Windows, too, so it is really a Firefox bug of some kind. -- Popup ads bypassing popup settings https://launchpad.net/bugs/76674 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
