On thursday 4/28/22 I lost the ability to use Gmail via firefox. I keep getting errors such as check your network connection and Oops... the system encountered an error (#001)

I have updated my browser on my windows computer, my network speed, upload and download speed is good. All other websites are functioning just fine. Only Gmail seems to be affected on my computer. (It works fine from other computers and from my phone.)

Do you know how I can make it work again? Please help!?!

Did you clear the cache/history and close and restart FF again but this time also disable Addons and see what happens.

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

This could be a problem with Zero Round Trip Time Resumption. You can try to set security.tls.enable_0rtt_data = false on the about:config page to disable this feature until this is fixed by Google or Mozilla.

You can open the about:config page via the location/address bar. Clear cookies the button to "Accept the Risk and Continue".

Hi! I've the same issue. I have the same version of Firefox in two laptops, the first one in use Windows 10 and last one Windows 11. In the same network. On Windows 10, I use Google Chrome for Work Account and Firefox for personal Account. I prefer Firefox by my employer is Google Fan and G-Suite works better in Chrome.

In Chrome I have no issue like my personal laptop with Windows 11 and Firefox.

In Firefox with Windows 11 sill lost connection at every 15 minutes. The only solution will be close Firefox and re-open if I no close Firefox the connection never be restore.

I delete and create a new profile, delete cookies and Web Cache. Disable the Enhanced Tracking Protection for Gmail. Go to History Manager and forget about gmail site. No solution for the issue.

Anyone can know what happen with GMAIL? Thanks
