Firefox 37.0.1 worked fine last night but today it times out and can't connect. All features function and connection is five bar. Tried disabling all add-on and re-install Firefox. No luck. IE works and I don't get any error message except that when I close FF and then restart it A message says FF is still running and needs to close old data. HG
