Cannot play 'framed' video

more options

I've made some security related changes via 'about:config' and now the Welcome video on the site https://www.dragon-claw.org/ does not play. There are no errors. It just doesn't play. This works in the firefox developer version. I can also view that video on the vimeo site, just not on this page. I started firefox in safe mode, but get the same issue so I guess it's some configuration I screwed up Thanks

Don't you remember what pref(s) you changed?

You can sort about:config by Status to see if you recognize prefs you changed. Otherwise you will have to remove prefs.js to reset all prefs.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Ok. Have renamed prefs.js to something else and restarted firefox. The video now plays correctly, so it's something in the config.
