Disabling the multi-process function of your browser, the setting "CPU threads" on the web page is still effective. You can see the single browser process using all your CPU cores.
Why does this happen only sometimes while most of time it does not (so many programs spawn several processes to try to take advantage of the multi-processor system)?

A program can be written to make use of multiple threads, thus allowing them to use more than one core.
A program can also be written to split itself into distinct processes, each with one or more threads to work.
There is a very subtle but real difference between multi-thread and multi-process. Disabling the multi-process functionality does not disable multi-threading, which was already present.
The recent browser updates to allow multi-process functionality enhances security and crash tolerance by separating threads for separate pages into their own process, each of those processes can still have multiple threads, all working independently.
