dom.maxHardwareConcurrency

I came across this while reading about privacy.resistFingerprinting.
This used to be an about:config option in old FF that used to be set to 2 (at the time this must have been the most common number of logical threads in the processor?)
Has it been removed in Pale Moon?

Have you checked for it in your PM's about:config first?

[noellarkin]

I did, it exists, but doesn't seem to have any effect. If I change it to 2, and then check from the browser console by running `window.navigator.hardwareConcurrency` I still get the system default.
This doesn't happen in Firefox. Changing it to 2 in FF and then running `window.navigator.hardwareConcurrency` gives me 2.

That preference isn't cached. You have to restart the browser for changes to take effect.

Please take note that this pref does influence how workers are handled. If you set it lower than your number of CPU cores/threads, then the browser will not use more than the max you set, reducing parallelism and efficiency. it is also clamped on the upper end by your hardware, so if you set it high, the actual number of cores/threads in the system will be used and reported.

Thank you! I restarted the browser and it worked!
