Just today, all the sudden my Firefox can't access to Gmail. When I try to login to my Gmail, it will shows:
Corrupted Content Error
The site at https://mail.google.com/mail/u/0/ has experienced a network protocol violation that cannot be repaired.
The page you are trying to view cannot be shown because an error in the data transmission was detected.
I have tried clear all the cache and cookies, and even start my Firefox in safe mode, I am still getting Corrupted Content Error
message when I login to my Gmail account. However, I am able to access it when I open my Gmail in Firefox private window.
What causes it? How can I fix it? Or I have to switch to Chrome browser in order to use Gmail?
