Switched to FF Nightly from Chrome about 6 months ago because Chrome's memory usage was awful. Firefox has been much better, especially since I modified the following in about:config:

    browser.sessionhistory.max_total_viewers => 0
    dom.ipc.processCount                     => 1

Isn't limiting the ipc processes severely capping (CPU) performance?
I haven't really noticed much of a difference in performance but memory usage is much lower.
It will cause all your tabs to run in one process, so only one CPU core can do work there.

This will especially be noticeable when multiple tabs are actively doing something, for example if you open up multiple tabs at once or background tracking script are stealing your CPU cycles.

Blocking tracking scripts and ads or just JavaScript in general can alleviate this to the point where you won't really notice.

It's a tradeoff, IMO.

Either you spare a few CPU cycles or a bit of memory. Though chrome doesn't seem to be doing good on either front.
