I'm almost totally unconcerned.
Browse with incognito for a start, browse with a VPN and at least one adblock addon.
You're probably going to be tracked one way or another unless you flush ever single cookie from your system and also use a tool that prevents fingerprinting.
Tracking is pretty avoidable really. Firefox in particular has a lot of protection built in like resistFingerprinting
. So Firefox + adblock + VPN/Tor probably blocks 99% of the stuff. It's not rocket science. Chrome on the other hand is hopelessly flawed.
