Firefox tab preview no refresh?

[brows]

I'm watching a YT video. It ends. Advertisements appear.

I switch to another tab to relax. 

Some ads are funny, others not.

I look at the YT tab preview if I can skip. But it's a steady picture.

So the feature should be: Open YT tab again after ads.

Between the ads you could play us a fox tune.
