AdNauseam by Daniel Howe

AdNauseam not only blocks ads, it obfuscates browsing data to resist tracking by the online ad industry. To throw ad networks off your trail AdNauseam “clicks” blocked and hidden ads, polluting your data profile and injecting noise into the economic system that drives online surveillance. The interactive AdVault allows you to visualize and explore the ads that AdNauseam has captured.

If you have either of the following settings enabled, make sure to allow AdNauseam in private browsing mode:
• History -> "Never remember history"
• History -> "Use custom settings for history" -> "Always use private browsing mode"
