I need to know where I can find the Content Process Limiting Setting in Firefox, it's gone, or is not where it is said to be located. This is the instruction I found. "uncheck the Use recommended performance settings checkbox to enable some hidden settings. One of those settings is the Content process limit setting, which can be set to a number between 1 and 8"

Its using up to much memory on my already slow processor.  

Please help me stop the extra processes.

Reduce the number of processes per tab from four to one by going to about:config and changing dom.ipc.processCount.webIsolated to 1. Make automatic tab unloading more aggressive by increasing browser.low_commit_space_threshold_mb.

Thank you for the reply. I changed the "dom.ipc.processCount.webIsolated" to 1.

 Can you be more specific, as to the "increasing browser.low_commit_space_threshold_mb" setting, how many MB I should increase to, it is set to 200mb currently. 

After changing the first setting from 4 to 1, restarting FF, I see no change in processes.

Visit about:processes (Shift+Esc) to see details of all the processes.

You won't see any difference with the first setting until you open the same site in multiple tabs, note how there is no longer multiple processes for the same site.

The second setting depends on your system, you will need to experiment with different values. Larger makes tabs unload well before running out of memory, leaving more space for other applications.
