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 HTTPatch

HTTPatch helps you test and customise HTTP headers in your browser. Set, append or remove request and response headers; group rules into named profiles; scope them by URL, resource type or browser tab; add Cookie, Set-Cookie and CSP rules with focused editors; pick popular header names from a searchable list or type your own; duplicate a rule; and pause all changes with one switch. Import or export profiles as JSON. Optional browser-account sync follows your profiles between devices and is on by default, including header values. No ads, analytics, account requirement or paid features.
