You can set this pref to 1 in about:config to limit the number of content processes.
- about:config => dom.ipc.processCount.webIsolated => 1
You can open about:config via the location/address bar. On the warning page, click "Accept the Risk and Continue" to open about:config.
It is quite normal to see more Firefox processes running.
- process for the main Firefox thread (user interface)
- one or more content processes
you see more content processes when Fission is enabled - 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 and Fission Windows
"Remote Processes" (Web Content)
