I recently upgraded to Firefox 4 and tried to book train tickets online. I have done this many times before with earlier Firefox versions. Now however, after being redirected to the card verification page and submitting my security details, instead of confirming my booking Virgin trains asks me to log on again! I thought it was a problem with the website but I subsequently booked the tickets using Safari so I guess that means there is a problem with Firefox 4. Can I go back to the previous version?

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete cookies.sqlite-journal and cookies.txt, if they exist, in the Profile Folder in case the file cookies.sqlite got corrupted.

I have since gone back to Firefox version 3 and feel much happier with it. I think the the problem I was having was due to the new version as I have made credit card purchases with both Firefox version 3 and safari without any problems.

I, also, have previously made credit card purchases with Firefox version 3 without any problems.

I only encountered this problem with credit card verification after downloading Firefox 4. I was however able to book tickets successfully, the same day, using Internet Explorer and the card verification went through as normal. I am confident that the  problem was due to problems with the new version of Firefox.
