I’ve noticed several posts over the past few years complaining about the memory usage of Firefox relative to Safari. I’m surprised about this: I’ve used Firefox on a few Windows laptops, and the performance has been stellar without using much memory. I’ve also used it on Linux, and the performance is comparable.

What’s different about Firefox on macOS? It seems like Firefox is a memory hog on MacBooks, but I want to confirm from MacBook users whether this is accurate. I bought a 2020 MacBook Air (M1), and I want to continue using the browser I love and use on a daily basis.
