Browser privacy product

Countering browser fingerprinting inside the browser.

Static is an independently built privacy extension for Chrome and Firefox. It responds to extension enumeration, browser fingerprinting, and session replay without sending browsing data to a backend.

Coverage
20+ browser API vectors
Platforms
Chrome and Firefox
Model
Zero backend / MIT licensed

01

Fingerprinting uses the browser as evidence.

Sites can combine extension probes and browser API behavior into signals that distinguish one browser from another. Session replay adds another layer of observation around how a person uses a page.

Static was prompted by the disclosure that LinkedIn probes roughly 4,500 extensions per page load. The broader product question was how much of that observation could be interrupted locally.

02

Keep the defense on the device.

Static blocks extension enumeration, browser fingerprinting, and session replay across more than 20 browser API vectors. Its protections run inside the browser without a service backend.

  • Chrome and Firefox support
  • More than 20 covered browser API vectors
  • No backend collection path
  • MIT-licensed source code

03

Return less useful evidence.

Static's opt-in Noise mode learns what a site probes and returns a stable, plausible decoy persona. Stability matters: random answers can themselves become a distinctive fingerprint.

The project is represented publicly through its verified behavior, browser-store listing, and source code rather than through unverified adoption or performance claims.

Privacy tools should reduce observation without requiring another organization to observe the user in the process.
