Ah, does it also have Pocket and Mozilla VPN and all the stuff I have to go into about:config to remove from Firefox too?

So, how painless is the transition from heavily customized and extended Firefox Developer Edition to Waterfox? Do I lose CSS support for multi-row tabs or compatibility with any extensions attained from the Mozilla store?

I already don’t maintain a Mozilla account or use any form of syncing, so “losing” that won’t matter.
