We find that using TorBrowser and #I2P are important first steps.
Purging #Cloudflare and all website that use Cloudflare including #banks, is is another important step. In #TorBrowser hit Ctrl+Shift+E to bring up the Network Tab, by looking at the domains the websites use you'll quickly see which are Cloudflare by the "cf-ray" in the HTTP response. The Block Cloudflare MITM Attack (BCMA) plugin can help.
The #UBlockOrigin addon is used by #TailsOS in TorBrowser, so use it.
