I can't open Gmail.

Even if I manually key into the URL:

http://mail.google.com/mail/

and hit the enter key, something expands the url to this:

https://mail.google.com/mail/?zx=1uk5vussgh1ej&zx=10vcl1iseyh
2f&zx=7qif8wmphjvb&zx=yrvynccdo648&zx=24huyak1i1ad&zx

[I added carriage returns so that the long line wouldn't mess up the bbs formatting... ]

and I get a Page Load Error from firefox saying

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

and

The browser has stopped trying to retrieve the requested item. The site is redirecting the request in a way that will never complete.

A similar thing happens when SWMBO tries to access Yahoo mail on this computer.

I have not disabled or blocked cookies; mail (from both Google and Yahoo) was working just fine a couple of hours ago. If I exit FireFox and restart it and try Gmail again, the same thing happens, but with a different batch of URL garbage. I guess next I'll try Dogbert's Tech Support (Shut Up and ReBoot) and see if that helps. Meanwhile...

Any ideas what is going on here?
