I’m not sure what to look for, but some more poking around tells me that it has to do with OCSP Must Staple. I was able to load the site after disabling security.ssl.enable_ocsp_must_staple. Nothing looks awry on the SSLLabs report but this is not my area of expertise, haha.
Well, one out of two ain’t bad I guess.
There’s a bunch of interesting smaller engines I hadn’t heard of on here before, though.
This list is remarkably comprehensive.
This is a very comprehensive list!
Anyone else getting a
MOZILLA_PKIX_ERROR_REQUIRED_TLS_FEATURE_MISSINGon Firefox 101.0.1 on this site? Works fine in Safari, though.101.0.1 (64-bit)
Works fine
Thanks!
Regarding the error: can you share more details? Which OS is this happening on?
If you open the “Network” panel in DevTools, what does it say when you click the main/top request?
This looks to me like an OCSP issue, which is odd since I use certbot-ocsp-fetcher.

I’m going to take this to DM!
https://search.marginalia.nu in particular seems fun for exploring the web, I found something interesting on my second search!
