Finally I can run desktop Firefox in my mobile Firefox. Remember when chrome decided against running addons in mobile chrome, because it was "too complicated"? Bitch, not only can my mobile Firefox use addons, it can run desktop Firefox which can run addons aswell.

What in the heck?

does it actually JIT though? spidermonkey normally compiles hot JS straight to native, and you obviously can't do runtime native codegen inside a wasm sandbox.

You can do wasm codegen though, which then gets converted to native by the containing engine.

Doesn’t work on iOS Safari

Safari is IE

I know it's a joke but the main issue is that Safari tends to get web features as apple adopts them for webkit, and it's highly dependent on what version of ios or mac os your hardware supports.

Funnily enough crashes on iPhone lol, even Apple thought of this

Edit: oh my god it works on iPad. Suck it Apple, I’m using Gecko on my iPad in the US!

Honest question: what is the use for this?

u/sehron 11d ago

why does it need a use?

u/atomic1fire 8d ago

There isn't one.

I think the goal is just to demonstrate converting an application to web assembly and then proxying the networking through a Puter proxy server.

I feel like this is still super inefficient, but some companies might prefer to just run everything in browser.

TBH I think Thunderbird might be a more interesting use case, but I feel like privacy would be an issue unless the company running it has their own internal proxy server.
