Funny you mention this. While Firefox’s interactive performance on Mac feels absolutely fine, it’s energy consumption is dramatically worse compared to Safari.
Using Firefox over Safari can cost hours of battery life, so it’s very hard to recommend it. Is this just a Mac issue?
I know of one issue with Firefox when you are using a scaled resolution. It absolutely destroys battery and performance for me. I _think_ it has gotten better with the latest versions but the tickets are still open.
