Thanks for the clarification - this is all acceptable in my eyes then. Of course I never use Google Search (prefer Qwant, StartPage and DDG) and location services are never running in my browser. Safe Browsing - I prefer not to have it enabled, but it's not such a risk if it is.
This is quite a different thing from using Chrome(-ish browsers) with the "phone home".
This is what it comes down to: I still use Firefox confidently despite being aware of these issues, as I'm aware they're still very minor compared to running Chrome, or even any other Google-engine-based project.
It's still however worthwhile probing these issues. They're still far from ideal, even if they're preferable as a "least worst" option.
