Firefox has some parts which are compiled to WebAssembly, and Mozilla wrote an article about it [0]. They seem to use WebAssembly to sandbox the code and improve security.

Firefox is weird. The compile to wasm and then aot-compile that to native code. It's purely to get C/C++ boundschecking and stuff like that everywhere
