I am using NoScript on Firefox, nothing else. When I tried to log in, first it made me go through a stupid password reset, that involved sending a plaintext temporary password to my email account, answer a security question, then force me to change my password, which I changed back to the original one. What a joke.

Anyway, in NoScript I had to "temp trust" pge.com, while leaving all those other links (the ones you listed and a few more) as "untrusted". So right now I am logged in, but there is a pop up asking (forcing) me to "update my contact info" in case of a Public Safety Power outage. There is a little 3-dot progress icon I can see in the middle of the pop up, like it's trying to refresh something. I can't escape the pop up unless I click on "Update contact info" (even though I have no updates).

So I did that, not actually updating anything, and now I see what you describe, a grey-ed out page with my info, but the little 3 dot progress spinner just running continuously, and my mouse cursor also spinning continuously when hovering over the page.

Follow up - I finally decided to make all the links temp trusted, and now I'm logged in "normally". However,
