Youtube slow or halting with update 150.0

Hi Folks,

I use FF since it was born and I cannot remember so many problems with Youtube. Youtube is slow or eben halting with update 150.0, in version 149.02 on Windows 10 and current hardware I did not face these problems. Initial "load ahead" always took it´s time, but now video playback as well as page layout is somewhat annoying. Please investigate.

Major issues here with Developer. I can shut off ALL extensions. Hit or miss. Using no extensions or all kinds of stuff...Discovery, ghostery & Ublock...and it works fine on standard version. It is a developer version issue with me. Page loads real slowly, usually with a blank space where video should be...even if the rest shows. Refresh can take a long time, if it even lets me refresh with out ctrl f5. Zero issues...so far...on standard version.
