I would love to understand that too. Especially since it seems to be a kind of UK problem. Colleagues in the US do have FF on their computers.

I'm not even allowed to run FF, Chrome, etc. We bypass this by using Waterfox because it seems to be the .exe Files that are blocked.

It's a horrible risk since people are doing research on their IE going down to private peoples pages and blogs (not all of them though since wordpress-hosted blogs are blocked...).
