Hypersegregate browsing with profiles.

One profile for banks, a different profile for Amazon, a third profile for Google sites, a fourth for news sites I log into, a fifth for news sites I don't log into, a sixth that automatically forgets everything on exit for sites that UBO breaks.

Then delete all data on each profile periodically, weekly for news sites, monthly for Amazon and banking sites.

It's a giant pain in the ass juggling all these profiles. Seems like there should be a browser that automatically and transparently isolates every site in its own profile.
