Undocumented functionality

Weirdly I've got a problem with Google today. I can't access Analytics from either Firefox or IE, but more annoying - I can't access my AdWords account from Firefox. Since Firefox is my browser of choice, that means a deliberate action to open IE so that I can view my AdWords numbers.

Since the analytics module seems to be down in both browsers, I'll assume that the issue is at Google's end. On the Firefox problem, I wonder if I have somehow got a cookie which is disrupting the AdWords access.

I'll try a restart later today but now I think about it, I had the same problem yesterday evening so a simple shut-down probably won't cure it.
