I was playing around with some SSL settings in Emby, and I managed to get this 'Secure Connection Failed' error which says:
An error occurred during a connection to emby.home.local:8920. PR_END_OF_FILE_ERROR
What is this error message trying to tell me? Is there any Firefox documentation where this error message is listed?

This error means that Firefox wasn't able to establish a secure connection and that all cipher suites failed (Firefox reached the end of the list).
Here are some thoughts about the cause:
The post says that you "was playing around with some SSL settings", so it is possible that you have specified some cipher variants that are not supported by Firefox or by the website you are trying to reach. Try to reset your settings to their initial state.
This can happen if you use a proxy or VPN or have other software that intercepts the connection and acts like a man-in-the-middle. Check your settings, and if using a proxy or VPN, try instead to connect directly.
It can also be the antivirus software. Try to disable or uninstall it.
Profile corruption is also a possibility. Go into
about:profiles
and use "Create a New Profile" and set it to default. If this is working, export your bookmarks from the old profile and import them to the new one and continue using it instead.
