No two issues are the same related there are many configurations and settings that also play into online streaming that can look the same but origin of problems aren't.

I solved my problem by downgrading windows from 1709 to 1703.Stuttering was on twitch.tv I was using latest drivers and latest flash player and fresh firefox install. It looks strange what only firefox was effected by windows fall update...

In this case, going to a previous version of the OS is not the answer.

I found on YouTube, that it defaults to playing video in HD . . . Simply lower the video quality to 360p, and no stuttering . . . settings are in the lower right of the video.

Netflix quality is always pretty good, because they have many servers, but you can adjust it there also, using Ctrl+Alt+Shift+S

Yes u can try to turn off your pc too for no stuttering.

LOL . . . try it . . . you get things to work by adjusting the settings . . . it requires new thinking, so is somewhat uncomfortable - that is what you are experiencing
