yes, FF is a memory hog.
im not a FF programmer, but each tab tends creates its on instance
so what you can do is a right-click on the disturbing instance and execute an End Process" to see which website was sucking up memory
It is quite normal to see more Firefox processes running.
- process for the main Firefox thread (user interface)
- one or more content processes, see:
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.
You can check the Firefox Task Manager (about:performance) and about:memory pages.
