The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.
About Overhead — HTTP Header Editor
Overhead is the header editor you can actually trust.
Add, modify, or remove HTTP request and response headers while you build and test web apps — and switch whole environments (LIVE, DEV, Staging, …) with a single click. Manage everything right from the toolbar popup: quick inline editing, header-name autocomplete, and one-click templates for the headers you reach for most (Authorization, User-Agent, X-Forwarded-For, CORS, and more).
Built to be trusted
100% local — your rules never leave your device.
No tracking, no analytics, no ads. Ever.
Open source, so anyone can verify it.
Uses Chrome's declarativeNetRequest engine, so the extension can't even read your traffic — it only declares rules the browser applies.

URL wildcard / regex / resource-type conditions.
Optional per-header display labels.
