The regular Firefox is much slower than Chrome still. The nightly is now noticeably faster than Chrome.
The current stable release 56 just can't compare to chrome.
Apparently they have decided 57 is stable already but plan to make it official tomorrow.
From my unscientific testing, 57 is only as fast as chrome, while the nightly (59) seems to be faster than chrome. They should have waited until 59 was stable.
I would be using the nightly as my main browser if I didn't have experience with crashes and bugs with nightly versions before.
They keep making it more and more like Chrome. If I wanted to use Chrome, I would. It's gotten to bloat maximum.
It's slow as hell. It's less flexible and less easy to personalize. They have broken some of my favorite add-ons.
This piece is pure propaganda.
It does break some extensions, but many have converted. Which are you having trouble with? The main one I'm missing is "Disable Ctrl+Q".

My main objection is still the sheer size and the amount of memory it takes, and the continual feature creep to make it more and more like Chrome. I know I'm in the minority, and also that it's heresy to say anything bad about Mozilla here. Oh well.
I only wish I had lots of money and/or time so I could help revive the development of xombrero, but at least it's still available.
Other options for Vim-like web extensions are Saka key, Vim-Vixen and Tridactyl.
