YouTube videos don't load in Firefox

[Sindy-S.R]

Before asking YouTube, I wonder if any of the forum members are having the same problem.

This week I started watching this video by Laura and many others in English:

I've been using audio subtitles and automatic subtitle translation (Spanish and Italian) for YouTube videos in English for a few months, but they no longer work this week. I've tried three different browsers: Firefox, Chrome, and Microsoft Edge (it doesn't have the audio subtitles option, but it did have automatic subtitle translation).
I've already tried the following, but with no positive results:
- Play DRM-controlled content
- Plugins Manager panel, Widevine Content Decryption Module provided by Google Inc.

I'm using Windows 10.

The video does show subtitles and the option to translate the subtitles in the settings of the video. I am using the Brave Browser, similar to Chrome.

If you're game enough to have a look at what problems are when loading any webpage, youtube included you can try this.

Go to the web page
Press F12 to open dev tools
Make sure the Console tab is selected on the dev tools window
Refresh the page / press F5
Look at the errors in the console window

For brave browser there will be quite a few like "net::ERR_BLOCKED_BY_CLIENT" but this is just the browser blocking ads and tracking scripts.

You might be able to see something there that gives you a clue as to what going on.

Hope this helps !

..., but they no longer work this week.

This week I had the same experience: I couldn't get subtitles.
Yesterday, however, when I asked for the English subtitles, I got French! Possible AI update?

Thank you very much, Bluekiwi, but I'm not at the level to understand and solve the problem with the dev tools.
But when I did, I saw many errors in the code.
I suspect this problem I'm having is related to YouTube's AI.
Well, now I have to ask YouTube directly.
