uMatrix is a browser extension that lets users point-and-click filter network requests by source, destination, and type, acting as a firewall in block-all/allow-exceptionally mode. It is a fork of HTTP Switchboard aimed at advanced users who can diagnose and un-break sites using its built-in request logger.

Use cases

  • block third-party scripts and trackers per domain
  • control which requests a website can make
  • filter network requests by type and destination
  • privacy firewall for my browser
  • allow or block cookies, scripts, and XHR per site
  • inspect and log all browser network requests

When to choose

  • you are an advanced user comfortable debugging broken sites
  • you want fine-grained, per-domain control over browser network requests
  • you want a strict default-block privacy firewall with a matrix UI

When to avoid

  • you want a set-and-forget blocker that never breaks sites
  • you are a beginner who cannot use a request logger to un-break pages
  • you need actively maintained software with recent releases
