I have my instances running set to 2. BECAUSE I WANT TO. Please don't try to explain why such and such is better. I am good.
Yet no matter what I tell Firefox, I may have up to 10 instance running with only one window open. Yes, I have the current process limit set to 2. I have the recommended block empty. I have tried it with "use hardware acceleration when available" checked and unchecked. it doesn't matter, Firefox still runs numerous instances..
How do I control this? it is eating up 30% of my memory at times.

It is quite normal to see more Firefox processes running.
- process for the main Firefox thread (user interface)
- one or more content processes, see:
Settings (Options/Preferences) -> General -> Performance
remove checkmark: [ ] "Use recommended performance settings"
- process for the compositor thread
- process for extensions
- process for WebRender when this feature is enabled
You can find the current multi-process state on the Troubleshooting Information page (about:support).
- "Help -> Troubleshooting Information"
"Application Basics": Multiprocess Windows
"Remote Processes" further down
See also the about:memory page for information about the process IDs.
If I set my instances to 2- why is is running more than 2? How do I make it run only 2?
For now you can only limit content processes (not instances). Beside these, there are a lot of different things, Add-ons, GPU, and so on. Everything is enumerated on the about:support#remote-processes page.
