I use the following in order of preference and frequent use:
Desktop (Windows)
Brave: I don’t need to block elements such as newsletter notices or annoyances, as those on Firefox using uBlock Origin do, since I really don’t care and it doesn’t bother me.
Firefox w/ Arkenfox: I use this as a fallback, or for logging into sites like this forum. Yes, I could do that on Brave, but I want to keep what I do on both browsers separate. A key difference is that I use uBlock Origin Lite, rather than uBlock Origin, although there seems to be some issues with the former currently.
Mullvad: For generic searches, reading information, researching for information so I can respond to queries like this, and the like.
Tor Browser: I somewhat use it for the same purposes as Mullvad, especially for anonymity.
Android (Plastic Premium Galaxy)
Tor Browser: Since I don’t use my Galaxy frequently, as I’m almost always on desktop, I mainly use Tor browser unless I need to sign in. Thus, I use Brave as a secondary browser.
Brave: I use this very similarly to desktop, except I don’t add exceptions since I can’t. (It’s either clear everything or manually clear what you want.) I simply just clear everything and deal with the inconvenience.
Differently to desktop, I use this also when I’m impatient with Tor Browser speeds, such as using Invidious on a .onion site, I just use it on Brave.
Mulch: I use this for sites I can safely stay logged into, like Cryptee.
