I've been having problems logging in on both Mac OS Safari and Firefox on desktop for a couple of months.

When attempting to log in, usually a log-in page will not load at all. If I manage to get my Comcast.net e-mail and password in, the page cycles endlessly and doesn't connect. (Come to think of it, this symbolizes my experiences with Xfinity support. Pretty sure I've spent hours trying to describe this problem to phone support agents and go nowhere.)

Typical error message:

The connection has timed out

An error occurred during a connection to xfinity.com.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

I cleared DNS cache on my computer, it didn't help at all.

I need to look at my account. When do you think you might allow your customers, who pay a lot of money for service, to log into Xfinitiy.com?
