Overview

Adds custom headers to requests

A lightweight and powerful Google Chrome extension designed for developers and QA engineers. It allows you to inject custom HTTP headers into web requests on the fly. ## Features **Global Injection:** Adds headers to all HTTP/HTTPS requests initiated by the browser. **Request Types:** Works with all resource types (Main frame, AJAX/Fetch, Images, Scripts, CSS, etc.). **Group Management:** * Create up to **3 independent groups** of headers. * **Toggle Groups:** Enable or disable specific groups instantly. * **Rename Groups:** Customize group names (e.g., "Staging Env", "Debug Tokens") for better organization. **Master Switch:** Instantly enable or disable the entire extension with one click. **Auto-Save:** All changes (headers, values, names, toggles) are saved automatically in real-time. **Conflict Resolution:** If a header already exists in the request, this extension **overwrites** it with your custom value. ## User Guide ### 1. Adding Headers 1. Click the extension icon to open the popup. 2. By default, one group is created. Click **+ Add Header** inside the group card. 3. Enter the **Header Name** (e.g., `Authorization`, `X-Custom-Token`) and **Value**. 4. The indicator **"Saved"** will appear at the top, confirming the rule is active. ### 2. Managing Groups * **Rename:** Click on the group title (e.g., "Group 1") and type a new name. * **Toggle:** Use the switch next to the group name to temporarily disable all headers in that group. * **Collapse:** Click on the group header (outside the input box) to collapse/expand the group card to save space. * **Delete:** Click the trash icon to remove a group completely. ### 3. Master Switch * Use the toggle in the top-right corner of the popup header. * **OFF:** No headers will be injected, regardless of group settings. * **ON:** Headers from enabled groups will be injected.
