I get the same on Firefox on Linux (Fedora 37). It looks like the server is responding with an ECDHE key exchange using a SHA1 signature algorithm which is disabled on modern versions of OpenSSL. I'm not sure why it works on Chrome, maybe their TLS client is a bit more lax. You can see openssl fail to verify the signature locally with `openssl s_client -connect blog.dijit.sh:443` due to the wrong signature type.
At least for me on Fedora, I believe Firefox uses the system policies and Fedora has set policies to block SHA1 signature algorithms https://fedoraproject.org/wiki/Changes/StrongCryptoSettings2....
