Firefox no longer plays embedded YouTube videos - message "An error occured, please try later"

I've updated FireFox, cleared cache etc., but continue to experience this issue on several different sites where I have embedded YouTube videos. This issue has only just started happening - all was well a few days ago. They play fine with Chrome and Safari and I can also play the un-embeded version on YouTube in Firefox.

Yes, unfortunately, another user reported this a few days ago on his website.

Currently the only workaround is to click the YouTube button in the player to launch the video in a new window, and then manually edit the -nocookie out of the address and press Enter to load it on the real YouTube site.

Hopefully someone at Google/YouTube will figure out why this suddenly broke and fix it.

The other thread: youtube-nocookie domain has problems in Firefox, but not in Google Chrome

Does it help if you change the third-party cookies to from visited?

You can allow third-party cookies only from visited domains.
