Process limit of the browser just a joke?
Hello, I have a fairly old notebook, so I need to watch the RAM usage. So what I did was limiting the process count of Firefox. I remember it working years ago on a different PC; but now it seems that this option does jack-shit. I limited my process count to 4 via the about:config method. But it seems the browser just doesn't care about it. I have 4 tabs open. One is Youtube, two others aren't loaded, and this forum. Task manager shows me Firefox has 9 processes. If I work and have like 5-6 tabs open, it goes up to 20 processes. Why is there an option if the software does whatever it wants anyway? How do I fix it?

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 disable Fission by setting fission.autostart = false on the about:config page. You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
