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
