For M$ no clue, for browsing,
AdNauseam comes to mind.
It's a fork of uBlock Origin,
which instead of blocking all the ads,
hides all the ads + clicks on them all in the background, which:
- Costs advertisers a lot of money
- Poisens your data profile, since they can't make up your actual interests anymore
It's more protest-ware then privacy-ware though,
since you'll be overflooding them with bs data,
instead of minimizing the data collected.
