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 Site Blocker

Add sites you want gone! As soon as you one, the tab closes automatically. When you block any site, its subdomains are blocked too, though a specific subdomain allow list is available. Has an on/off switch and a "Focus 30 min" button: blocking locks on for 30 minutes, then you get a 5-minute break.
