Does the ports version of Firefox 139 support SNI?

[trev]

I spent almost a full day trying to get SNI working on Apache for two web sites on the same IP address before discovering that it actually works using Safari on macOS, but not with the ports version of Firefox on FreeBSD. The classic failure symptom is the second named virtual host trying to use the certificate of the first named virtual host.

So, can anyone confirm whether the ports version of Firefox supports SNI?

It does, make sure your certificates contain the hostname in its CN and in the alternate DNS names.

That sounds like a server configuration issue, not a client issue.

The certificates match both the CN and the alternate DNS name.

I'd agree, except it works perfectly with the Safari web browser on macOS which rather rules out a server misconfiguration.

And of course when I go back to try it today, it all works as expected with Firefox and Seamonkey for that matter. <shrug> May have been a cache issue...
