I think the arkenfox project website has some good info on this. For a good privacy baseline, you basically only need to enable strict mode and download the ublock origin extension, then change some settings for the extension (e.g. add filter lists).
I love the fact that I have no modern annoyances. No cacophony of binging noises to warn me about every small pointless thing: a car passing me, minor speeding, upcoming cameras, a car braking in front, reversing towards an object. Nice and quiet… just the hum of the engine. I don’t think I can drive a ‘new’ car.
The weather can change quite quickly in the mountains. It was winter hiking anyway, but suddenly dropped as we neared the top. Thankfully, there is a cable car station at the top of Kasprowy.
