Support for font-variation-settings has been on by default since Firefox 62, which was released almost two years ago. Are you using a Firefox older than that?

Ah, sorry, I was looking at the wrong item on "Can I Use...", @font-face: font-variation-settings, rather than the "Variable Fonts" item which covers font-variation-settings outside of @font-face rules.

And I am running an ancient version of macOS, 10.12, which explains my issue, as it's only supported on macOS 10.13+ in Firefox.

I have a new (non-macOS) laptop in transit, but my current daily driver is an old Mac.

Sorry for the alarm!

Nice. For comparison, here is Mozilla's implementation in Rust, which is integrated into Firefox: https://github.com/mozilla/neqo

There's a great series of posts going into more detail about Pernosco's design and advantages that is linked to in the final paragraph: https://pernos.co/about/

On https://codetribute.mozilla.org/ you can find mentored Mozilla project bugs to work on (not just Firefox) indexed by language.

And this is landing very soon in Firefox, behind a pref. https://twitter.com/svoisen/status/1159322370122768384

As of yet, the browser support for this is very shoddy. Not to mention outdated/legacy browsers like IE.

It's probably referring to this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1089326

Firefox and Servo use 1/60 as the smallest layout unit for the same reason.

It's cool and all, but keeping that decision has led to some pretty annoying bugs in SVG (and other) transforms.

Unfortunately for me, the fact that rr can't run on Ryzen CPUs is a dealbreaker. :(

I am wondering why this isn't getting more attention.

Can someone with a technical understanding describe what's going on here? Is this a flat-out bug- or does the x86 architecture spec allow for this?

Awwww :( That's really sad.

rr is important enough for C++ development that I agree it's dealbreaker.

There are minor benefits without ABP. For each page/iframe that is created, we can avoid running the CSS cascade (and share those data structures) for the UA style sheets. It's saves something like 100 KiB per document.

If other add-ons insert a common style sheet into all documents (it's plausible Stylish does something like this? though I've never checked) then we'll again be able to avoid running the cascade and having duplicate data structures for the cascade across different documents.

I just wanted to take the time to thank you for fixing that bug. Since I keep dozens of tabs open all the time, the memory consumption of FF has caused me a lot of pain (the browser gets really slow if it crosses 2.5GB real RAM consumption).

So, you just made my life better, thanks :)

Cheers!

Interesting that Firefox takes the decomposed Hangul and renders it as whole syllables, while Chrome shows them as the sequence of individual jamos. http://mcc.id.au/temp/hangul.png
