Firefox 70 is suppose to have a big performance boost on Mac.

Firefox 70 will use Core Animation on Macs for graphics rendering, just like Chrome and Safari. This will vastly improve low energy consumption/battery life, but I haven't heard anything about general UI performance?

Anyway, it's supposed to be out next week [1] :)

I'm on Firefox Nightly, and performance has been noticably better in the past several months.

Previously Firefox was barely usable for anything with animation on OSX. They've been making steady (if slow) progress for the past year or so, now it's subjectively on-par with Chrome and Safari for me.

Does this mean that watching video via firefox on OSX will no longer make my machine heat like crazy?

Firefox performance has been a joke on mac for years with "fixes" supposedly happening every few months but it's still horrible. I'll believe it when I see it.

> The performance is not stellar on OS X and plugin support is tiny by comparison so I find myself drifting back to Chrome.

Are you saying that Firefox has less addons than Safari? Is that even possible with the restrictions on Safari browser (ads blocking)?

I’m assuming that they’re comparing Firefox to Chrome.
