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?

The fan keeps the circuit board from burning up. That means CPU.
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

The fan is still coming on. If Firefox uses too much CPU how do I change it?
Is this different from using too much RAM? I thought Chrome used more CPU (or whatever uses up GBs/storage), that's why Firefox was recommended.
Let's start with the fan first. In most computers today the fan is controlled by a thermostat inside the case. Too hot = fan on. Okay = fan off.
Sometimes, there is a problem with the fan itself. Sometimes the air vents get clogged. Get a can of compressed air and blow out the vents.
Place your hand over the exhaust vent. Is it blowing out okay?

Is this the only time the fan gets a workout?
