I still recommend it. I'm not fully happy with the situation but for now I consider it my best option.
- I consider Chromium-based browsers out of the question as they give too much power to Google. This is already showing to be a problem with new APIs and "features" that Google is pushing into the web platform and the bigger the market share gets the more control they have.
- Web browsers are the biggest attack surface that most people have. Displaying untrusted webpages and running untrusted code is incredibly difficult and vulnerabilities are regularly discovered. I don't yet know a Firefox fork that I trust enough to reliably respond to security vulnerabilities quickly and correctly.
So for now I am staying with raw Firefox. Not to mention that as a disto-built Firefox I have some insulation from Mozilla's ToS. But I am very much considering some of the forks, especially the ones that are very light with patches and are mostly configuration tweaks.
