On the first screen I started downloading the emulator Bluestack with active Firefox, on the second was active another window, it does not have to be a startup task. As you can see on the second screen, the task distributed 4 threads. And if you work in the Mozilla browser, any running program/task works only in 2 threads and starts terrible brakes and in the Mozille. There are no such whores in other browsers!!!

Downloaded Waterfox and with it everything is OK, and Waterfox herself distributes the load on all 4 threads and the other programs also do not go to 2 threads

Those are called Processes and not Threads.

Chic answer, it is a pity that absolutely illiterate yes and useless

Note : Intel is not Firefox. Good luck on Waterfox https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Multiprocess_Firefox

Do you have enabled "Resist Fingerprinting" if you check this pref on the about:config page?

cor-el Thank you man, for participating. The first and second parameters are defaults by default and 16 respectively. Third not aboout: config.

reinstalled Mozilla after half a year and she still works only on 2 threads. Unfortunately, I used to really like this browser. Have to use others

And why did not you remove then the nonsense that wrote that "helper"? The problem was solved by itself, after the last major cumulative update, the Windows system settings were reset and Firefox began to work correctly on all four THREADS!!1

Apparently the bug was in the system itself because of which it worked incorrectly with firefox
