When I enter my email address and password, nothing works

I don't need to re-set my password because it works just fine. My problem was / is not in getting access via ID and password. I can get in OK, and have done it any time I try. I should have been more precise. After getting in via ID and password, there is something which you offer to new participants to search something (I have no idea what it was) to see if any friends are in Twitter. At that point, you offered a place to enter ID and password. That's the point where nothing happened when I entered my working ID and working password. I have since tried several times to get back to that offering and cannot find it. As a result, I have no idea if there are any friends who are in Twitter.

When I enter the email address and password that BT gave me, they appear to be both wrong. why is this? Someone please let me know.

I had this problem with Firefox with NoScript 1.8.1. I updated to 1.8.1.3 and the problem is solved.
