I find it interesting they compiled SpiderMonkey to WASM to run JS in its interpreter mode when it already has iOS support built-in via the interpreter. I would've thought all of the performance enhancements could be done without involving WASM at all. As far as I'm aware the only reason why Firefox for iOS doesn't use SpiderMonkey is App Store restrictions.

The wizer approach to reducing JS interpreter startup time can't work with the iOS built-in interpreter.
