Not sure you'd want to apply for a job at a place that makes broken web sites.

Sounds like they need help, no?

Wouldn't want to work there myself, but to somebody on HN who's trying to "race their browser" it seemed a feasible workaround.

That was a bit of creative license. I'm aware that's not exactly what is happening and know that there are workarounds (which I use), but it definitely can feel like that, and given the context of the thread, I thought it made sense.

Where's the pause JS button ..?

You could stop by adding a breakpoint, for sure, but it seems like you're suggesting there's a method accessible to normal users? An addon. (I'm on FF but interested if there's such an option in any other mainstream browser).

The solution is to choose between a footer with links and infinite scroll. It's really simple, since choosing one should preclude choosing the other.

Yes. This is one of my methods for dealing with it. Another is to just inspect the source and look for the relevant href. Point is, don't have a footer with links if you are using infinite scroll!

An average user wouldn't be able to, websites shouldn't do this in the first place.
