Headers Manager per ArabCoders

Headers Manager is a powerful extension that lets you modify HTTP request headers for any website using customizable rules and URL patterns. Perfect for web developers, testers, and privacy-conscious users, it enables you to add authentication tokens, CORS headers, custom user agents, remove tracking headers, and override browser navigator properties.

The extension features an intuitive interface with reusable header templates, website grouping, wildcard URL matching, and real-time toggle controls - all while automatically managing storage to sync your configurations across devices or handle large rule sets locally.
