For the lng run there needs to be a solution for the WhatsApp Monopoly we all live on. I mean, this argument is several years old and what can we do to change that? You could start by trying to convince some og your contacts to switch zo signal. In terms of co convinience their app is the closest to WhatsApp.
I’m using Mull but am going to switch to Fennec with arkenfox hardening and ublock enabled in the future.
IMO don’t use too many privacy plugins like ublock, privacy badger and jshelter. Ublock can also block individual scripts in expert mode and therefore reduce your fingerprint to a minimum. Additionally more extensions also mean more consumed ressources.
I would also reccommend a secure dns filter like nextdns or the one from mullwad. I use Rethink dns for the configuration. https://www.f-droid.org/en/packages/com.celzero.bravedns/
Here is a site from Germany that handles many privacy topics and has a section for dns servers: https://www.kuketz-blog.de/empfehlungsecke/#dns
