Unfortunately Firefox still has a lot of issues when it comes to font rendering on macOS. For example, it's been two years and it still renders San Francisco incorrectly: https://bugzilla.mozilla.org/show_bug.cgi?id=1721612

Not to mention all fonts appearing bolder than they should compared to Chrome and Safari. It might seem like a small thing but I'm a stickler for typography and it really stands out on a Mac.

I hope they get around to fixing these issues but two years is a long time for such an obvious bug. What confuses me is how few people have noticed given that it seems to affect all Apple silicon devices.

Interesting, must be only happening on some native MBP displays. I'm on an M1 MBP and haven't tested it on an external display but it's definitely noticeable on mine, although not as big of a deal as the letter spacing thing

I confirmed the letter spacing is still an issue by comparing the "How I digitize books" paragraph on Chrome and FF. I had to override the CSS as the site has switched to "Newsreader, serif".

I don't see the fonts appearing bolder difference (on my 4k screen). Actually that's not true, I have seen differences on lower DPI displays. I get around that using BetterDisplay to enable HiDPI on the external. I've also never noticed San Francisco font rendering improperly which I only would if it didn't fit in a clipped box.

Now that performance is largely improved, maybe they'll get around to fixing this one.
