Hi thanks for filing,

I cannot reproduce the issue so far, could you try two things:

• open the browser console (https://firefox-source-docs.mozilla.org/devtools-user/browser_console/index.html) and then try to "inspect" the youtube logo. Copy paste here any error that might appear in the browser console
• go to about:support and copy the information to the clipboard and attach it here

And if you can also try with a clean profile, that would help find the root cause of the issue.

Thanks!

Hi Julian,
you can close this case. I confirm that Firefox 99 has fixed the issue, and now YouTube HTML inspection works perfectly.
