Oh FFS

For a long time now I have been wondering why I can't login to my Nationwide account in linux. There's no error message, I am just returned to the login page, which isn't very helpful. This evening I decided to try a fresh firefox install. So I started firefox with -ProfileManager and created a new profile. And I could login. I don't have a lot of plugins installed, in fact the only one I could think might have any effect modifies the referer, I usually have it set to not embed the referer. It turns out the Nationwide site needs the referer. So there you go if you've been wondering about it too.
