My suspicion is that it is not html5.
I say this because, even though I was cruising youtube, I was not playing anything. Furthermore, I used an addon to block all ads, so I had no animated ads, nor any ads on the pages. So, I am puzzled about what is eating the cpu bandwidth. I wish there were away for the user to view all the JS directives that FF receives from the web sites so we can know exactly what it is doing. We need to able to exercise total control over what the browser is doing on behalf the websites we visit.
the wonders/whats/whys of programs are, i believe, in many minds is "!WTF! is happening now?".
i will give some credit to the firefox dev's in that they did foresee need to know 'wtf' and some of access is via "Tools" in 'main menu' bar.
they did think to include, at one time, what is called "error console" and "browser console".
"error console" is accessed by pressing <alt+t>,<alt+w>,<alt+c>. along top of "error console" window are buttons for:
[All] [Errors] [Warnings] [Messages] [Clear]
where the active button with be enclosed.
if not available for your version, which you did not mention, for more info see;

and
https://developer.mozilla.org/en-US/docs/Error_Console
https://developer.mozilla.org/en-US/docs/Tools/Web_Console
"browser console" is accessed by pressing <alt+t>,<alt+w>,<alt+b>, or, <ctrl+shift+j>. along top of "browser console" window are buttons for:
[Net] [CSS] [JS] [Security] [Logging] [Clear]
where the active will be clear, inactive is grayed. each of the buttons has a color which relates to color used in the log table.
again, availability depends on version. for information, see;
https://developer.mozilla.org/en-US/docs/Tools/Browser_Console
to see if you have some add-on causing loading, in 'main menu' bar, try;
Help > Restart with Add-ons Disabled...
if loading drops, you have an add-on causing problem and you find which one by restarting firefox with 1/2 add-ons enabled. if ok, enable 1/2 of remaining, restart, then repeating '1/2 enable' each time until add-on is found.
