People here seem to "hope" that extension support will be implemented.
If my stable Firefox for Android gets updated into a browser without uBlock Origin I will immediately switch to some chromish alternative with adblocking. There's no reason for firefox for android once extension support is gone, featurewise.
I use Firefox for Android for one reason: the ability to not load images on cell data. I'm surprised other browsers don't have that, but it's huge for me since I pay by the megabyte (Google Fi). It saves me $10/month easily.
edit: oh, it looks like that's missing, too. Nooooo....
I am on a slow university network and I keep JavaScript off by default using UBO. It takes 3 clicks to enable it for sites that really need it, but web is much faster with it.
