decent for now but behind in terms of cookie / tracker blocking. It's always a race, code and these battles are fought literally daily. Until it goes blockchain with a thing like Fractal Protocol, it's a rough bet. Any later browsers and you risk security issues. Tldr it'll work, as will firefox, it maters what else you slap onto it, opsec, and how your base computer security is. Using windows or mac? Guess what. You have bigger problems. Final note is that no one is immune from hardware hacks, os zeros, browser extensions, phishing, etc. Don't be stupid. Just because I listed win and mac doesnt mean that linux kernels are immune to problems from shitty installations or faulty browser maintenance
