Manifest V3 Rule Spec

Declarative Net Request Engine Under the Hood

Instead of running slow JavaScript event listeners, MS Technet Secure registers high-speed rule sets compiled directly into Chrome's native C++ network parser:

// declarativeNetRequest Rule Sample (ms_technet_rules.json)
{
  "id": 1042,
  "priority": 1,
  "action": { "type": "block" },
  "condition": {
    "urlFilter": "||doubleclick.net^",
    "resourceTypes": ["script", "xmlhttprequest", "sub_frame"]
  }
}

The Technical Architecture Behind MS Technet Secure

Traditional ad blockers ran heavy JavaScript regex engines directly on every open browser tab. This often resulted in high RAM consumption, fan spin-ups, and artificial lag when switching tabs.

MS Technet Secure is engineered around Manifest V3's declarativeNetRequest API. Instead of executing scripts on page load, the extension registers pre-indexed matching trees with the browser's native networking layer.

Zero Injected Scripts: Eliminates page script injection overhead for standard ad filtering.
Zero History Logging: Network rules match on pattern tokens without storing URL logs.
Auto-Updating Filter Lists: Filter definitions for EasyList, EasyPrivacy, and MS Custom Defense update silently in the background.
