Unfortunately that's also where I'll stop during at least a few months after Firefox 57 is released. Quantum is ultra fast, but my extensions are more important. Greasemonkey and Stylish, for example, have equivalent WebExtensions, but they're not as polished. Same with DownThemAll.
I think WebExtensions should have matured a bit longer, with Quantum, electrolysis, and Photon being made available for all with the old extensions.
