How to reduce the number of firefox.com running?

If you notice you have more content processes than in the past then you may have Fission enabled. Fission is about a new site isolation architecture in Firefox and you will see more Firefox processes running than before and when Fission is enabled you can no longer limit the number of content processes in Settings or via dom.ipc.processCount on the about:config page. You can check the current Fission state on the "Help -> More Troubleshooting Information" (about:support) page (search for Fission). You can set fission.autostart = false on the about:config page to disable Fission.
Stopping fission reduced the number of firefox.com running from 12 to 14 down to 8. I've edited the number of content processes (several times) down from 8, but it always returns to 8. Seems there should be a way to further reduce the number of Firefox running.
hey its really weird because its only on one website today i have 16k ram and still going up
It is quite normal to see more Firefox processes running.
- process for the main Firefox thread (user interface)
- one or more content processes
- 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).

"Application Basics": Multiprocess Windows
"Remote Processes" further down
See also the about:memory and about:processes pages for information about the process IDs.
