I'm getting an error connecting to an HTTPS website with Firefox of
SSL_ERROR_NO_CYPHER_OVERLAP on Fedora 33. How do I see what ciphers
Firefox is configured to use?
When I use a public scanner to see what the site supports, it appears
that there are multiple secure ciphers available, so I don't know why
Firefox doesn't like them (and it doesn't provide any more information).
The site in question is https://support.juniper.net/.
I understand adjusting Fedora settings to require good security, and I
know I can lower security system-wide, but no debugging info is not
good. And really - having to lower system-wide security settings to
allow connection to one site is a poor design.
See https://bugzilla.redhat.com/show_bug.cgi?id=1893581 and
https://fedoraproject.org/wiki/Changes/StrongCryptoSettings2
In the second link, see the section on " Upgrade/compatibility impact"

The key to getting good answers is to ask good questions.
