Gmail again showed the same error message. Both websites opened now but when I tried to open the websites again after some hours. I opened Gmail and Outlook websites and pressed Ctrl+F5 keys together to reload the webpages from scratch without using browser cache. I tried to reload the page a few times and every time Firefox showed the same Corrupted Content Error message. Nothing worked and the problem still persisted.

Restarted Firefox in Safe Mode with add-ons disabled.

It was my Mozilla Firefox web browser which was showing that error message while opening the websites. Gmail and Outlook websites were not down.

So it was clear that the problem was occurring from my end not the website end. I tried to open Gmail and Outlook websites in other web browsers including Google Chrome, Opera, Internet Explorer and Microsoft Edge present in Windows 10 operating system and both the websites opened fine without any error message in all other web browsers. Only Gmail and Outlook websites were throwing the above mentioned error message in Mozilla Firefox web browser. In fact other Google network websites such as Google+, YouTube, etc were opening without any issue. Same error messages was displayed for Outlook website: The site at has experienced a network protocol violation that cannot be repaired.Īll other websites were working fine. Please contact the website owners to inform them of this problem. The page you are trying to view cannot be shown because an error in the data transmission was detected. The site at has experienced a network protocol violation that cannot be repaired.

Firefox won t open gmail
