It also feels laggy to me. It's weird given the reports of all these other users. I am also using a 16GB Ram, Intel Iris MBP. There is a noticeable pause while switching tabs, and there is a very noticeable lag while typing (for example in this box). Pages do seem to render fast, but it feels very laggy in terms of user interaction. Edit: The scrolling is also very laggy, which I forgot to mention, much more so than Chrome.

Check about:support and look for a number higher than 0 in the "Multiprocess Windows" entry. Old extensions or something may be keeping you from running multi-process.

  I have a 1/1 there, and the only extension I have loaded is the new version of Tree Style Tabs.

  I use a magic trackpad for scrolling and the delay before scrolling is there in either case, but it was off.

  FYI, Chrome has had smooth scrolling since v49. https://developers.google.com/web/updates/2016/02/smooth-scrolling-in-chrome-49 https://developers.google.com/web/updates/2016/02/smooth-scr...

I haven’t had any lag in text entry, but I ran the Windows version for a while (making sure I gave it plenty of time to build up a cache) and my general perception is that Chrome is still faster. I like the idea of switching to Firefox a lot, but from a performance perspective I’m not seeing quite what everyone else is.

The typing lag put me off immediately. I've measured the input latency and its ~3x slower than chrome. Filed a bug around a month ago https://bugzilla.mozilla.org/show_bug.cgi?id=1408699 https://bugzilla.mozilla.org/show_bug.cgi?id=1408699
