Kagi's Orion browser has a lifetime sponsor price of $150. That plus the Kagi subscription support its development.
It's currently macOS and iPad/iPhone only, but a Linux version is being worked on. I don't know their plans for a Windows version.

Also, they claim "zero telemetry", so I don't really know what's going on, I know it's not leaving my computer.
I find that currently even if it's far from perfection, Orion is the lesser evil in the browser scenario.
Accounting for lifetime anything is hard (I don't know how to do the math, I'm sure people that do debate a lot of complex issues), but I'm again going to suggest that a lifetime subscription needs to be 20x the yearly fee to give a number to start the debate at.
