A great reason to choose Firefox (Score 4, Informative)

There is another story about JS loading with IE7 & IE8. According to 4 of my testers (and a test I did after using the same environment), it seems that we can't login to our site so dep using Internet Explorer 7 and 8, on Win XP (and maybe Vista, not tested). After validating the form, we are back to login page, without any error, but like we are unauthenticated. On the other hand, Firefox does its great job.
