What Traffic Blocker does
Every rule you add is translated directly into a ChromedeclarativeNetRequest dynamic rule. Chrome enforces these rules at the network layer — matching happens before a request reaches the page, which means blocked resources never consume bandwidth or slow down rendering.
Wildcard URL patterns
Match entire domains, subpaths, or protocols with patterns like
*://*.example.com/*.Initiator filtering
Restrict blocking to requests that originate from specific domains, or exclude trusted initiators.
Priority ordering
Rules are matched in the order they appear. Move rules up or down to control which takes precedence.
Blocked counter
A live counter tracks every request blocked since the extension was installed, resettable any time.
