youtube videos won't play ... again in 106.0.5 update

[jostan]

Inability to play YT vids was a major problem about a month ago -- I could run them in Chrome, Edge, and Brave. Then recent FF update fixed the problem ... for about a week, until 106.0.5 installed a few days ago. Again, YouTube hangs with spinning arrow in FF, and again Chrome, Edge, and Brave are OK. I've tried ALL the suggested search solutions and none solve the problem. Very odd that there are no postings HERE about this, as I have seen many other users report the same problem in other forums going back many months. Could this forum be "edited" in some way???

Same here. YouTube embedded video are also ok with Tor and my smart TV's browser (Linux).

Having switched to Chrome I may never go back to Firefox

 This screenshot shows the error that appears after a while. I've had to put a warning about Firefox on my website: 11th November 2022
Firefox cannot currently play embedded videos. Please use another browser e.g. Chrome. (Microsoft Edge also works.)

Same problem. After upgrading to version 102.5.0 esr, yotube videos stopped working properly.

Same video problem for me.

During the past couple of month since September, Firefox sometimes does not play videos on Youtube, BBC, Cbc.ca and other websites. Not sure if it is because Firefox setting is controlled by Group Policy of my office to disable auto update.
What I tried to fix it:
- Refresh the webpage, sometimes helps.
- Restart Firefox. Sometimes helps.
- Disabled Hardware acceleration, but Google Maps becomes very slow.
- Enabled 'Auto play' in Settings.
- Uninstall Firefox, then re-install Firefox.

But my another laptop still works fine on Firefox. - FYI

Chrome, Edge does not have this problem. Hope Firefox team can fix it so I don't have to switch to other browsers.

This problem has existed for the last couple of months after Firefox did some updates. Support is poor for Firefox and nobody has come up with a solution. Firefox responds with guesses as to what the problem is. Security software is blamed but that software doesn't affect the other browsers.

If security software is related I would like share that we recently updated Cylance anti-virus software. Trend Micro anti-virus has been used for years.

I have a similar problem running two instances of FF, one served by Apache and the other by Hugo server (real time monitoring). Hugo server displays embedded YT videos properly; Apache server does NOT, resulting in a very odd message from FF in the embed window stating that:

Firefox Can’t Open This Page

To protect your security, www.youtube.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

It is VERY strange that the identical site behaves differently depending on the server in effect. The identical site displays embedded TT videos properly in Chrome and Safari. FF on ipad works okay too. Only FF on Linux when served via Apache fails. And ONLY with FF, no other browsers. This is very disappointing.

I also switched to FF from Chrome, and I like FF better, but I'm going back to Chrome if this YT embed pro9belm isn't soon fixed. Why should FF care if I am embedding multiple instances of a video? Why shouldn't I be able to do that??

All replies to my original post interestingly seem to have their own unique story. But all also say that other browsers work fine -- just FF fails. I should have mentioned in my post that I am running Win10 on a Dell desktop, with very fast internet service from Spectrum. And my problem is still on-and-off from day-to-day. Yesterday, YT vids ran fine at startup. Today, they fail again. Will I restart my system, which may or may not work? No. I will just switch to Chrome if I need YT vids. Sidenote: my YouTubeTV service works fine, despite annoying buffering problem sometimes.
