Jake,
I'm a bit confused about your statement suggesting turning off browser password saving and autofill. Could you explain the dangers of not doing so please.
As an aside I installed Brave last night on both my desktop and Android 8.0 phone. Imported logons, passwords, bookmarks, from FF to Brave without issues. That import function is not available in the mobile version.
No issues at all.
FWIW I have Brave 1.18.78, Firefox 84.0.2, Waterfox Classic 2020.10, and Edge 87.0.664.75 (all 64-bit flavors) on my Windows 10 [Home (x64) Build 19042.685 (20H2)] desktop. Everything functions fine in all of these although I've made Brave the default and never use Edge unless a page won't display in any of the other browsers which, thankfully, has become much less of an issue in recent times.
Trying Qwant per your suggestion. Had been using DuckDuckGo with their Privacy Essentials extension....
I'm also running Comodo Internet Security Premium (firewall and anti-virus) and use Malwarebytes and their adwcleaner every 2 days.
