I'm also very impressed with FF's performance on Linux in recent versions. I bumped up the RAM allocated for multiprocess but I never really have more than 20 tabs open. Startup and rendering seems much quicker, and the add-ons seem more open.

I'm curious, if you go to about:support are HW_COMPOSITING and OPENGL_COMPOSITING enabled? Someone (likely here) mentioned that setting layers.acceleration.force-enabled to true in about:config makes a dramatic difference in performance, and based on my limited experience, it does. So much so, that I'm thinking about switching to Firefox after many years of only using it sparingly due to lousy performance on Linux compared to Chrome (e10s has helped too). edit: I should note that HW_COMPOSITING and OPENGL_COMPOSITING are not enabled by default on the 2 Arch Linux systems I have (Ivy Bridge and Haswell iGPUs, up to date Firefox, Mesa and Kernel). Not sure if there is a white/blacklist, or if its just always disabled in Linux.

  Is there a particular reason that layers.acceleration.force-enabled is off by default?

    Linux users have a lower priority and there are some hard to debug issues with graphics drivers and sometimes it causes horrible performance and freezes. https://bugzilla.mozilla.org/show_bug.cgi?id=ogl-linux-beta https://bugzilla.mozilla.org/show_bug.cgi?id=ogl-linux-beta
