Well, you’re right in principle, but with my (old, but current) Mac+Intel configuration Firefox is not as sleek as Chrome and also often Firefox turns the fan on while Chrome doesn’t (it may just be that Google is bricking Firefox when you’re on YouTube, for example)
Anyhow, I’m trying to use Firefox as much as I can (I’ve always done so), but it’s always been true it was a better experience to use Chrome on my setup (and I’ve never used Safari)
Edit: why the downvotes? To teach me a lesson? I said he’s right, but I do have an actual problem and cannot yet make the full move (and am going to check out the suggestions below. Thanks!)
I finally had a minute to try it out and unfortunately it does not seem to change anything on my 2020 Mac+Intel (the GPU load skyrockets when I watch videos on YouTube)
