Description
Add, set, or append custom request headers per profile — with import/export and ModHeader backup recovery. Add, edit, and toggle custom HTTP request headers, organized into switchable profiles. Request Header Modifier lets you build a set of header rules (name, value, and whether to Set or Append) and flip them on or off from the toolbar popup, no separate options page required. Group related headers into named, color coded profiles and switch between them in one click, useful for juggling staging, QA, and production setups. Features: - Inline add, edit, enable/disable, and delete for headers, right from the popup - Profiles: create, rename, delete, and switch instantly - Set or Append per header, with a clear warning when Chrome does not support Append for a given header - One click extension wide on/off switch that leaves each header's own state untouched - Export a single profile or all profiles to JSON, and import them back - Automatic light and dark icon and popup theme, matching your browser All data stays local in your browser.
