Mozilla has also put significant effort into improving their C++ GC in Firefox, e.g. switching from a non-generational one to a generation GC[0] and then to a compacting one[1]. Just like Google can both improve Chrome and work on Go, Mozilla both improves Firefox and works on Rust.

Those are all about the JavaScript GC, right? Not using the GC for actual pure C++ objects.

I wasn't giving examples of Mozilla doing exactly what Chrome is doing, just counterexamples to your implication that working on Rust means no work on improving memory management in Firefox.

That said, it's not even like a single-GC approach is incompatible with Rust: https://blog.mozilla.org/research/2014/08/26/javascript-serv...
