Sandbox your browser in a VM or something. Don’t use the same browser/VM for banking/personal stuff and everyday browsing. Most browsers should work. (Except Chrome/Edge/Opera/Yandex). Personally I prefer Firefox. LibreWolf can also be an option, but you have to opt-in to see videos with DRM etc. Tor is also an option, but the downsides are captchas and websites that block you.
If you’re even more extreme you can also use uBlock Origin in “hard mode” and the no script toggle. That will block JavaScript and prevent websites from connecting to any 3rd parties, anything from tracking servers to CDNs. That will definitely break websites, so you’ll have to know how to unbreak them, which can be quite the learning curve for some people.
Why not Chrome/Edge/Opera/Yandex you say? Chrome is owned by an advertising company. Edge tracks you plenty. Opera and Yandex are made by companies from authoritarian states.
