Status: RESOLVED WONTFIX

(Core :: Networking, defect)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

I had enabled http3 in about:config at some point in the past. Firefox had updated to 79.0, and I had restarted my browser.

Disabling http3 in about:config entirely resolves the issue.

Not a system clock or certificate trust issue, clock is fine and certificates are trusted and within expiry.

Not a network issue, happens over OpenVPN to a public VPN service, Wireguard to my server, and no VPN at all.

Actual results:

I was unable to get onto www.google.com, screenshot of error attached. I was able to get onto google.com.au and google.co.uk, once each. After that, all of those pages gave me the same error screen.

Expected results:

Either getting the page with no error, or even an SSL error code would be nice. I see in console, there's a message about not having an SSL error code, so I'm guessing this bug is deeper than a certificate error.

Dragana, Andy, I think this is a known problem with h3 on google.com?

This is a know issue with 79. Http3 is being developed at the moment and we cannot fix this issue on 79.
