Show HN: Firefox in WebAssembly

A developer showed off something delightfully absurd: the real Firefox browser running entirely inside a browser tab. In plain English, that means someone got Firefox to appear and work inside another browser window, like a digital hall of mirrors. And the community did what the community always does when confronted with genius-meets-chaos: it immediately turned into a mix of awe, confusion, and meme warfare.

The loudest reaction was pure comedy. One commenter dropped the classic browser-in-a-browser joke — "Yo dawg" energy was off the charts — while another gleefully reported that you can run Firefox-inside-Firefox-inside-Firefox... though apparently only if you enjoy living dangerously. That discovery instantly pushed the thread from "cool demo" into "how far can we break reality before it breaks us?"

But there was also a serious side bubbling under the jokes. One technically minded commenter was fascinated by the speed tricks under the hood and wanted details, suggesting there may be genuinely important ideas here, not just a stunt. That created the thread's tiny drama: is this a breakthrough or just a wonderfully cursed party trick?

Then came the funniest buzzkill of all: someone pointed out it apparently doesn't support Firefox mobile. Nothing kills the sci-fi magic faster than "works in a tab, not on your phone." So yes, the project impressed people — but the comments made clear the real star was the spectacle: equal parts innovation, recursion, and internet clowning.
