Firefox 84 brings native Apple Silicon support on macOS

Prasad, 16 December 2020

Mozilla has released version 84 of Firefox across all three desktop platforms. The big news with this version is that it adds support for Apple Silicon on the macOS version, making it the third browser after Safari and Chrome to do so.

Starting with version 84, the macOS build of Firefox will now natively support both Intel x86 and the ARM-based Apple Silicon processors, including the current M1 SoC and all future models. While the previous version did still work on these newer machines, it would run under emulation through Rosetta whereas version 84 runs natively.

Running natively means it can fully benefit from the performance of the new architecture and the processing power of the M1 chip. Mozilla claims version 84 launches over 2.5x faster and web apps are 2x as responsive compared to version 83.

The update process is the same as before. Go to Menu > Help > About Firefox and you'll see the option to update to version 84. Once done, restart the browser and it should be updated. To confirm if you are on the native ARM build, type about:support in the address bar and you should see a suggestion below saying Rosetta Translated as “false”. You can also check Activity Monitor to see if the program is showing up as ‘Apple’ or ‘Intel’ under the Architecture tab.

As for other changes in version 84, it also includes WebRender for macOS, Windows devices with Intel Gen 6 GPU, and Intel notebooks running Windows 7 and 8. Additionally, there's an accelerated rendering pipeline for Linux/GNOME/X11 users along with more modern techniques for allocating shared memory on Linux, improving performance and increasing compatibility with Docker.

Finally, Mozilla has also said that version 84 of Firefox will be the last to include support for Adobe Flash.

I didn't mention tracking so why do you bring it up? I don't mind being tracked for marketing purposes, what I'd have a problem with is any kind of government tracking me. But Firefox provides very good anti-tracking options if that�...

Google is not their sponsor. They pay them for implementing Google search bar. They pay every other browser for doing that.
