Silence is sadly no longer maintained, but it still seems to work for now. I will eventually replace it.
Re Mozilla: I do state on my browser comparison page that Chromium browsers are more secure. Also the Bromite repository is included in F-Droid by default on DivestOS.
Few quips:
Silence was last updated (on F-Droid) a year ago — is this project secure//being maintained?
& Mozilla-cousin browser: you're going to lose the security clout these days unfortunately.
