Go to about:config and change dom.ipc.processCount to a high number. You'll get the behaviour you want. Four is a reasonable default, especially given that multi-process is so new. It's possible that the default number may increas

Plenty of people were left scratching their heads when the new Google Earth was introduced, precisely because it was clear that PNaCl's days were numbered. I think the likely explanation is that Google is a large company with numerous

Adding multi-process support is the single biggest change ever made to Firefox. It was enormous. That's why it took so long.

Er, what? Labor came up with the idea of the NBN and started it. The Coalition then stopped building it properly and switched it to the watered-down version when they gained power. The Coalition deserves the blame here.

There is a little-known Valgrind tool called "DHAT" (short for "Dynamic Heap Analysis Tool") that's designed to help find exactly these sorts of excessive allocations. Here's an old blog post describing it, by

Mozilla is the only company that builds a browser because it genuinely wants to, rather than as a market defense tactic.

I run Nightly on all my machines, and in my experience its stability is good. YMMV, of course.

> I have animations that run at a smooth 60fps in Chrome and Safari effortlessly, quite often producing 1-2 FPS in Firefox. Can you give an example? I'm sure Mozilla's animation people would love to hear about this.

Move semantics are so useful and powerful, but so complex. I've read multiple tutorials on them (all of them very long) and I still keep forgetting minor but critical details. (You could probably replace "move semantics"

Rust code is also going into Firefox, slowly for now, but it will speed up over 2017.

It's perfectly reasonable to say "Rust isn't appropriate for my use case". Your comment higher up was more along the lines of "Rust isn't appropriate for anyone" which is far less reasonable.

Adding multi-process support is the biggest single architectural change ever made to Firefox. It was started, then put on hold for a couple of years because it seemed insurmountable, and then started again. It's taken a huge amount of

I too would like that! But lots of other changes have been landing concurrently, so it's hard to isolate the effect of my changes.

Author of the post here. A lot of the heap allocations I removed were small and short-lived. So I believe just the malloc/free calls themselves -- and whatever synchronization and data structure manipulation they entail -- are most of

Mozilla has been gradually restricting what add-ons can do in Firefox precisely because of problems with malware. This is another step in that process.

> It should not recompile those crates each time, if it does, that's a bug. Please report them! Depends on the inter-crate dependencies, alas. Touching one crate can easily cause multiple other crates to rebuild.

If you click the "[-]" symbol at the top right of a docs page it collapses all the text and just shows the method signatures. Then you can click the "[+]" symbol next to any single method to get full details.

NZ and Australia have very different fauna. They might look close on a world map but the distance from Sydney to Auckland is over 2000 km. Just one example: Australia has a wide variety of mammals (mostly marsupials, e.g. kangaroos). NZ has

My post indicates that I've already removed a large chunk of the existing mallocs. The remaining ones are harder, but I expect I'll be able to still remove a decent fraction.
