"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

OS: Fedora 36 Firefox Version: 104.0 (64-bit)

What the OpenH264 plugin is for https://support.mozilla.org/en-US/kb/open-h264-plugin-firefox

One package to make sure you have installed on Linux is FFmpeg so you can fully support the HTML5 players used for video, audio and games on sites like Youtube, Twitch and news sites.

Yes, I am aware what the plugin is for and I already provided a temporary solution to the problem, this is just a bug report for that issue to be fixed by the Firefox devs. Things are working fine for me now that the plugin has installed, problem was just getting it installed since the HTTPS certificate for the domain it is downloaded from is invalid.

I'm not sure why Firefox would upgrade such a http:// link to secure HTTPS to access a server that doesn't support secure connections and only works with http://.
