But is it? I wanted it to be tongue-in-cheek but the title is actually a rather accurate description of the contents of the article. This is a ~20 lines weird hack that we threw at the wall to see if it would stick... and it massively improved Firefox stability. I can't stress it hard enough, it's the largest, most visible stability improvement in the past decade.

More specifically - on the memory front - we spent lots of engineer/years working on improvements which sometimes would barely register, only for some weird trick make OOM crashes fall off the radar entirely.

Also I'd like to point out that we have no way to tell if this is working because we give Windows time to resize the swap file, if it's because other processes in Firefox die, or it's because other unrelated processes die, or a mix of all the above. It's pure speculation on our part.
