I'm personally like to stop using Brave, and I will, however while LibreWolf will be what I'll switch to on desktop, I'm not sure what I would want to switch to on my Android phone. I see that LibreWolf doesn't have an Android version (and potentially never will; fine, developers will do whatever they want). I've heard about IceRaven, however, I'm not sure how good it is. Also would like an actually privacy focused search engine, but I think LibreWolf might have a good list on that front.
(Note: please do suggest in replies, not sure I made that apparent)
Check out Mull or Mulch. Mull is a more private Firefox and Mulch is a more private Chrome. They are made by the DivestOS team, they also make DivestOS which is a lot more private Android version that supports a huge number of phones. That's how I'm also runing the latest version of Android 13 with the latest security updates on a phone from 2019. And there are much older devices supported.
Since I'll be moving to LibreWolf and it's based on FF, I'll check out Mull. Unfortunately I don't see my device on DivestOS's site (it's a Motorola Moto G Power 2022), but it's also quite new so it's understandable. I'll switch it to Lineage or something like that whenever it gets support for it but I'm fine with a degoogled Android for now.
