ProfileFog

Blur the profile they think they have on you.

ProfileFog helps blur low confidence ad and tracking profiles by combining controlled browsing noise, tracker blocking, link cleanup, learned tracker controls, and local Chrome privacy settings.

Ad networks and trackers build profiles by watching patterns. ProfileFog changes the pattern. It adds controlled browsing noise, reduces tracker reach, cleans tracking tags from links, and gives you simple controls when a site needs a lighter touch.

Why ProfileFog exists

ProfileFog is built around the idea: make your online profile harder to trust.

Classic tools like AdNauseam and TrackMeNot showed that privacy can also come from obfuscation. AdNauseam popularized ad profile obfuscation by adding noise to advertising surveillance. TrackMeNot hid searches inside a stream of decoy searches. ProfileFog brings that same privacy intuition into a Chrome Manifest V3 extension

What ProfileFog does

• Adds controlled search and browsing noise
• Blocks common tracker requests with Chrome Manifest V3 rules.
• Cleans tracking tags like campaign IDs from links.
• Learns which tracker domains repeatedly follow you across unrelated sites.
• Gives you current page controls when a site acts weird.
• Lets you pause protection on a site without digging through settings.
• Supports cookie block mode for learned trackers.
• Adds local Chrome privacy controls where Chrome exposes them.
• Lets you export and import your settings and learned tracker data.
• Flags possible CNAME cloaking when first-party subdomains look like tracking endpoints.
• Watches canvas, WebGL, and audio fingerprinting signals without blocking or spoofing.
• Uses a stronger bundled public suffix map for cleaner domain grouping.

Why people might want it

• Make weak ad interest profiles less reliable.
• Reduce third party tracking while browsing.
• Clean ugly tracking links automatically.
• See which domains keep showing up across sites.
• Keep quick breakage controls close instead of buried.

Version 1.7.0

Added a stronger public suffix map, CNAME cloaking watcher, and fingerprinting watcher. These are watcher-first features: they record suspicious signals for review and logging
