With all due respect, I cannot confirm this. Even after applying all the about:config settings you suggested at the Gathering 2018, and making sure firefox was completely shut down and a new instance spawned, it was still slow as molasses compared to PaleMoon 27 with xrender enabled. To be honest, I didn't see a single speed improvement from the part of your changes that I hadn't already applied, compared to stock Firefox. Well, what should I say? It is quick here and very usable with FF 60.3.0esr. I am writing this mail with this FF.
Actual line speed:

The only thing I noticed is that I still have BIG-REQUESTS disabled because Thunderbird and possibly evince would crash with it (and the X2Go packages installed here are from X2Go stable, and dated before the Gathering 2018, so do not contain your BIG-REQUESTS fixes yet).
*Maybe* the speed-up effect you're seeing is only possible with BIG-REQUESTS enabled?
Looks like there are updates available for both firefox-esr and X2Go since, so I'll try updating and see if and what that changes.
