Which browser do you use and why?

I use several, depending on use case:

• Tor Browser for general and anonymous web browsing (e.g. reading news, looking up stuff, and so on)
• Mullvad Browser as a clear web alternative for general use
• Librewolf for generally logging into sites with personally identifiable accounts (e.g. to buy stuff)
• Ungoogled Chromium for those few sites which only work with a Chromium-based browser, or other specific cases
• On Android (GrapheneOS): Tor Browser and Vanadium

All regular browsers have some hardening applied and uBlock Origin installed.
