Actually that is not bad at all. How much ram do you have ? is this causing any problems of unstable or over heating ? It is a multiprocessor and multi-thread browser. It is suppose to work that way. Firefox, sandbox, extensions (which use give or take 20megs each) also a few more that bring up processes.

Is the box for Prevent Accessibility programs from using your system checked ?

Multi-proccesor Can completely disable it this way in about:config : dom.ipc.processCount set to 1 browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false

Or move to the Extended Release Version 61esr Firefox ESR does not come with the latest features but it has the latest security and stability fixes.

But backup before you do :
