I still have to test #31125 on linux, but we should probably merge those 2 at the same time.

Last time there was a problem with compiling firefox, is this resolved now?

[Mic92]

I currently try to build firefox with this pr.
UPDATE it still fails to build

[vcunat]

Firefox fails due to these:

I tried backport some of the fixes from firefox 57 but it's getting kind of messy, perhaps we should start versioning rust like we do with other compilers?

[GrahamcOfBorg]

Do you mean for 17.09? We should backport all the browser updates, and not fret about individual FF patches.

No, FF 57 is not released yet and the current version doesn't build with rust 1.21.
