Thanks. Uploading a version on my website is not an option because Firefox won't let you install it if it hasn't been signed by Mozilla. Everyone is forced to wait for the Add-ons team to review and publish the upcoming version. The slow review process kills all my efforts to fix bugs quickly.

Thanks! If you know what about:config is, set dom.security.trusted_types.enabled to false

I know, and a new version that will fix these issues is pending for review since Jan. 30, 2026

The review process is extremely slow on AMO, and one of the reasons I left for a while.
It's so slow that I already have another version ready, but I don't upload it yet otherwise the pending version will lose its position in the queue.

Thanks!

Thank you

Thank you. I don't see the bigger related videos yet, so I guess it's another A/B testing and you've been selected.

Thanks for the feedback!

Thanks. Please wait for the upcoming version that is pending for review since days, it will fix this issue.
You can also use this as custom theme to quickly fix it now:

body.efyt-cinema-mode:has(#movie_player.ytp-fullscreen) #efyt-background {
display: none;
visibility: hidden;
}

A new version is pending for review since days. I hope it will be available soon as it will fix your issue.

Thanks, and yes I agree, but I'd say all the time :)

Please wait for the upcoming version currently pending for review, it will fix this issue.
