Comcast email doesn't work for me

I installed fresh and when I go to Comcast to retrieve my email through their website I log in to the site and click email. It opens up a new tab and just shows a spinning thing forever. I tried setting up a new profile and that didn’t work. If I run IceDragon in safe mode it works! So I tried disabling all stock addons and am running no theme like suggested in help. I also disabled hardware acceleration like suggested and nope. Any suggestions or help would be appreciated.
