I switched to Pale Moon in light of Australis but actually think that the new version of FF is a big improvement on that in a lot of ways. Not sure where it's getting its settings from if this is different to what the rest of you are seeing but I'm seeing a much cleaner UI, and the browser itself seems pretty fast. It's also loaded my adblocker and password manager just fine. Still not sure I'll be switching back fro Pale Moon but that'll do me as a start.
