Description of problem:
When we access the url "https://mail.google.com/mail/u/0/" an error appears on Google web site saying "Temporary Error - Numeric Code: 9".

It is related to having a saved account, I tried to download original firefox/bzip2 manually from Mozilla site, and this behaviour did not happen. 

Even reinstalling the RPM from Fedora repository, and cleaning all cookies or ".mozilla" folder anything did not change.

Version-Release number of selected component (if applicable):
Firefox 82.0.2

How reproducible:
Just try to access the website using an account logged in.

Steps to Reproduce:
1. Log in https://mail.google.com/mail/u/0/ for the first time
2. Try to close tab/browser or enter again in https://mail.google.com/mail/u/0/, the page should enter automatically in Gmail account
3. Temporary Error pages appears

Actual results:
Temporary Error

Expected results:
Already enter the website normally, without asking login again.
