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 CORSet!

Allows to make cross domain request with the MV3 API only on user's selected tabs. (https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) Click on the extension's icon to enable/disable CORSet on the current tab. A small icon will be placed on the bottom-right side of the screen to remind you that CORSet is active on the current tab. Browsing the WWW with CORS hurts really bad your system security, enable it just for development and on tabs where you really need it.
