@Turd_Ferg PC (Linux): Librewolf for some things (fediverse, news outlets, mail providers, etc), Waterfox for other things (especially sites/platforms where I need to write Portuguese, because Librewolf's "Resist Fingerprinting" breaks accent keys), upstream Firefox for more mainstream things (government services), as well as Lagrange for Gopher and Geminispace.

Smartphone (Android): Fennec, with native Chrome active against my will for WebViews from certain apps (governmental and banking apps, for example) that require Chrome For My Security™.

It's been a while since I ditched Chromium-based browsers, although Firefox has some Chromium things inside its code. I'm waiting for whatever browsers that could bring third-party browser engines besides Chromium and Firefox-engine (yeah, there are Pale Moon, Basilisk, Safari/Webkit, among other browsers which are neither Chromium nor Firefox-based, but I'm talking about a browser as compatible as possible with features such as WebBluetooth, WebGL, WASM and other things as they can prove useful for personally-developed projects/self-hosted services).
