Firefox pain with youtube

Hi

I am trying to use Firefox to browse youtube but the youtube page always hangup like 10 seconds then I can see the page also playing any video is very slow and many times the play stop to buffer !! using chrome has no problems at all but I like to use firefox is there a fix for this problems ?

This is what I see for 10 seconds:

Disable FireFox add-ons extension to see if one of them causing problem.

Which build version? 32 or 64 bit?
I'm NOT able to reproduce your issue.

I don't have a problem in my 64-bit Firefox 115.7.0 ESR as well.

But when I disable Javascript (by an addon that I can use for sites I want to disable Javascript on) I get about the same result. It only happens directly, not after 10 seconds or so:

So, indeeed, maybe some addon is interfering. Switch off all addons/extensions to be sure those are not conflicting with Youtube.

I switched off all plugins but I get same result

Make sure that this happens only with FireFox browser, check other web browsers.

Delete Temporary internet files.

Install the newest version of graphic card.

yes chrome work fine
