I have a problem. When I open multiple YouTube video tabs, the CPU slows down even though the "Use hardware acceleration when available" option is enabled. Is it possible to make the browser use the graphics card to reduce CPU usage, or does this only depend on YouTube?

Another issue I'm having is that YouTube no longer lets me adjust the size of the thumbnails, so they appear too large and can't be resized even with zoom. It would be great if you could find a solution to these problems.
