Every time I try to access hotmail in firefox I am told:

"Error symbol The Windows Live Network is unavailable from this site
for one of the following reasons:

* This site may be experiencing a problem
* The site may not be a member of the Windows Live Network

You can:

* You can sign in or sign up at other sites on the Windows Live
Network, or try again later at this site."

I've tried deleting cookies and clearing cache but no success. Should
I try uninstalling/reinstalling Firefox?
