Shrapnel have fixed the attack - that was on Friday, so you should not be seeing that any more. That was discussed (a bit off topic but we all do that
) in the MBTs thread at
http://forum.shrapnelgames.com/showt...=45260&page=20 at post 960 or so onwards.
I use Firefox as well, and use ghostery and privacy badger as my ad blocker tools - the web would be unnavigble without these, unfortunately!, and have no problems with the website, including logging in.
(I tried Chrome as an alternative while the problem was active, it still opened the pop-up tabs but unlike Firefox, about half simply opened a blank page - so some of those redirects seem already to have been auto-marked as spamvertising by Google in thier browser).
