The Mozilla bugzilla allows me to logon via Github, but when I logon it tells me that my account is disabled. But then it says to request it be reenabled from the login page... does anyone here know how to get around this issue?

Might be worth contacting the BMO team at https://chat.mozilla.org/#/room/#bmo:mozilla.org

As a diehard Firefox user, it has never been competitive with safari when it comes to performance. JavaScriptCore and WebKit are kind of ridiculously fast. If only they were put in a browser that was at all usable.

Have you tried Safari 14? I recently upgraded and they’ve finally fixed the address bar race conditions and swipe back/forward lag which drove me away in previous versions.

Sorry to but in but do you perhaps know if they've addressed the issues that made me switch from Safari to Firefox maybe 2 years ago? I listed them here https://news.ycombinator.com/item?id=25132068

If you are a dev be careful with these new macs. Docker won't start: https://news.ycombinator.com/item?id=25073010

Docker has already addressed that, and a link was posted about it yesterday in HN.

We wouldn’t want facts to get in the way of {mis, dis}information.

From what I've read the performance is very competitive even for Rosetta apps. Native support will just make things even more astounding.

It looks like you lose about 30% performance to Rosetta. That's quite a lot, and makes it slower than current x86-64 processors, e.g. Ryzen 5000 series, or even the Ryzen 3000 series. But compared to x86-64 Macs it's not that much slower, because the x86-64 Macs are using old slower Intel CPUs.

And that's for static code. Chrome runs like garbage under rosetta for me, with frequent stutters, presumably because of the cost of dynamically recompiling freshly emitted code.

Would you mind posting that here?

Firefox doesn't stutter on infinite scroll sites like Twitter. Safari noticeably does, even in Big Sur. So I am torn between the two.

I have the exact opposite experience, FWIW.

You can change the title to "Firefox beta supports Apple silicon natively" (edit: or "Firefox nightly and beta support Apple silicon natively", the current "Firefox nightly (beta)" is ambiguous).

It's actually a marvel that it can even JIT translate the output of another JIT...
