TLS problems with Firefox on bugs.tryton.org and downloads.tryton.org

Posting this in case others are also walking into this.
I’m using Fedora 30 with Firefox 67 installed with dnf. When I go to the bugtracker or downloads. I get

An error occurred during a connection to bugs.tryton.org. Peer could not decode an SSL handshake message. Error code: SSL_ERROR_DECODE_ERROR_ALERT

Searching showed me an old post to lower the TLS-requirements in the about:config section of Firefox. So I did go to about:config -> accept the risks -> TLS -> change security.tls.version.fallback-limit to 3. In my case the limit was 4. After restarting Firefox I was able to reach the bugtracker and downloads section again.
