Safari is SO much more efficient than Firefox. I find it to be more performant while also using a lot less juice on my MBP.
Before my next trip I want to get a VPN configured so that when I am remote I can 1, access my home network/lab and 2. Take advantage of pihole (not to mention encrypting my traffic)
I’m making it sound easier than it is, but it’s still pretty straightforward. There’s actually a doc on the official pihole site that explains how to do this but I haven’t read it completely.
Then there is tracking and sometimes even malware...
Plenty of them out there for iOS and macOS and they work well.
