Firefox is pretty good, use Tor-Browser if you are more paranoid, otherwise just install a few addons and you're more or less safe.
A few I recommend/use:
Cookie Auto Delete
Decentraleyes
Firefox Multi-Account Containers
PrivacyBadger
Temporary Containers
uBlock Origin
advanced:
NoScript or uMatrix
advanced-er and super paranoid:
