Why are there 20 to 30 instances of firefox in my task manager when I have just 2 tabs open? It is bogging down my old laptop. I got directions to fix it from Mozilla Support, by turning off recommended performance settings and lowering content limit from 8 to 4 [although directions said I could do that right there, but I couldn't and had to go to config.] After a restart, I currently have just one tab, and there's 12 firefox, and it had gone up over 30 originally. I did a whole bunch of end tasks, but they keep coming back. Why can't I force it to only open 1 firefox for each tab? I don't want all that extra crap!

FISSION: The links are sites explaining the Firefox's Project Fission. This is the reason for the processes you see in task manager. You can turn fission off by setting it to false on the about:config page. see screenshot Here is more info. https://www.ghacks.net/2016/02/15/change-how-many-processes-multi-process-firefox-uses/
