HeaderMod bởi ibaciu6

HeaderMod lets you modify HTTP request and response headers using rules you define.

Features:
- Multiple named profiles of request/response header rules
- Per-rule enable/disable
- URL filters (regex) and resource-type filters
- Tab lock — apply a profile only to the active tab
- Pause / resume all rules without deleting them
- Cloud backup — timestamped profile snapshots via browser sync
- Import / export profiles as JSON

Built on Manifest V3 declarativeNetRequest. HeaderMod collects no data and makes no network requests of its own. Host access is optional — grant it once from the popup ("Enable on all sites") and rules apply only to the sites you allow.
