There is some misunderstanding here what Mozilla did with Fx 57.
It is basically a cleanup with some new parts. No big rewrite of
anything. Extensions usually do no longer work not because of new code
but because of code removed and some tightened security. Minor code
changes caused a big impact for extension compatibility.
Not said that they didn't do a good job speeding up Gecko but I already
saw this in 2.53 /56.
And if you take enough code out and switching the user interface to
mostly vector based black and white images with dull gray background and
empty boxes e.g. the add-on manager you get a shiny new fast release.
The next planned release after the last in the ESR 2.49.x branch is 2.56
ESR. If it comes to this it will allow classic extensions to install.
But because of code removals most of them will just no longer work and
would need to be updated.
When running 2.55a1 and a page throws extensive javascript on it it
slows down as it did before. I expect the same with Fx 57. Probably not
so noticeable because of e10s in Fx but for everyday usage I fail to see
the speed improvements. Startup times may be improved if you use a lot
of tabs because fx delays loading them better but if you actually try to
use them ram will go up fast. And if you think every tab is isolated and
runs in its own content process now think again. There are only a few
content processes and some tabs will be use the same. A 2.49.2 x64 on
Windows is pretty darn fast enough for me.
As usual my findings may not be accurate and YMMV

It will also mean saying "Good bye" to all of the extensions and add-ons
you've been counting on for years, as the new Quantum engine is a total
re-write of Gecko. Until ADP changes their time sheet application, I
can't afford to switch to anything past the current state of Seamonkey,
or the Firefox ESR version of their browser. I like getting paid... it
helps me maintain my addiction of having food on the table and a warm
dry place to sleep at night.
