Obviously there a people in charge now who will never understand the Streisand effect. They could have kept it quiet and just... allow... the technical adept users to do their thing. Now, they are the laughing stock and get unwanted attention. Also, from my layman understanding, this shit won't fly in the EU at all.
Or, to say it differently: This is the best thing to happen to Mozilla in quite a long time and I'm a fan.
I'm out of the loop. What happened? Did someone decompile their code and find definitive proof of a throttle for Firefox?
JavaScript is an interpreted language, so no decompilation is necessary, although this is repeatable by using a Firefox user agent.
You can build a virtual machine in JavaScript and execute compiled code on it
Just because you can...
Oh yeah, you shouldn't. But people do this for fingerprinting, bot detection, and other "adversarial" scenarios where you really don't like the person executing your code. It's somewhat plausible Google would use this technique to do something scummy like this (although that is not the case).
