About this extension
🌐 Monitors browser network for all tabs and pages in a single extension window. Track network traffic including request headers, cookies sent from each tab, and corresponding response headers and cookies. Filter and capture only required requests, exclude unwanted ones, or block specific requests entirely. A powerful network monitor and HTTP inspector for developers — inspect headers, edit cookies, intercept requests, and modify outgoing headers without leaving the browser.

From the captured data, you can filter requests to view based on various attributes, clear all captured data, compare with previous/different requests, single page to see all the traffic in a centralized place instead of each tab.

✏ Add/modify the request headers before sending the request — for all requests, a domain, or a single URL (supports Cookie, Referer, Origin, Host, and custom headers).
🍪 Delete all cookies for the selected domain, or for a domain of your choice.
