How come Xfinity's website is always ridiculously slow

Good morning @user_7d4wax, and thank you for taking the time to leave us your feedback about the XFINITY website. I will pass that along to our dev team to review. If you have a smartphone, head over to https://www.xfinity.com/apps to download the XFINITY app.  The app is a great one-stop shop to handle multiple things for your account. You mentioned making changes to your account, is there anything that I can assist with?

Every single time I sign in, the website is extremely slow or useless, and yes, I already checked my internet speed and other websites, this is the only website that is very very slow and this is a recurring problem, it happens all the time not just once. Every time I get the message "We are having some trouble connecting to My Account." It is hard to believe that Xfinity, being an internet company, has such ghetto speeds in their own website. It feels like its on purpose so no one can make any changes to their accounts. This is also why I would never even consider to have a phone plan with xfinity.

How many extensions does your browser have?  Have you tried disabling some to see if that makes a difference?
