Comment (by cypherpunks):
Replying to [ticket:21675 gk]:
> We should avoid leaking the amount of cores a user has available by
asking `window.navigator.hardwareConcurrency`. Not sure which value we
should give back and if we should return the same one for all users.
Of course, one! Are you sure asking to give workers of one site more than
1 core?
Maybe, this can help:
{{{
// return the maximum number of cores that navigator.HardwareConcurrency
returns
pref("dom.maxHardwareConcurrency", 1);
}}}
