Why does my Macbook fan come on watching videos with Firefox but not Chrome?

The main reason I still use Chrome is to keep my laptop fan from turning on when I watch YouTube videos. This then leads me to use Chrome for other reasons as well. I would prefer to use Firefox, but I don't like it when my fan turns on. My Firefox is up to date according to me preferences page.

I have tried unchecking "Use hardware acceleration when possible" and restarting Firefox, but the fan still comes on.

What's the solution?

I have been using Firefox for more than 10 years now. it is the best browser out there. However, starting from last year I have been noticing that my computer's fan is almost always working which takes too much of my battery and I figured that Firefox is the main issue (I did so many research and tests %100 sure). Later, I herd about the new Firefox quantum, and decided to wait and not switch to another browser. the new one was released and I installed it the very first day. I was super happy that it's much faster and use less memory than other browsers (that's right). However, lately (about a month) I noticed the same the fan is always working again, so I check the task manager and found my dear Firefox quantum acting up again even though 3 taps are opened.


I really need help with this issue to stay using Firefox, I am tired of this issue and really considering switching to another browser because this is just not good at all. and I could not find any way to fix it. please see the attached pic it's just unbelievable.

FF uses 100+ CPU on my otherwise totally fast up-to-date MacBook. This, despite doing all the fixes suggested, repeatedly.

It has gotten so bad that it constantly overheats my Mac, causes my fan to go on full blast non-stop, even when it's in the background, so I basically have to stop using it.

Mozilla needs to get serious and overhaul this heavy-use browser.
