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 PolyFills for Windows 7 Chrome

Injects javascript to handle features that don't exist on Windows 7's version of Chrome. This includes things like CSS4's ":autofill" selector, Set.prototype.difference, Array.prototype.toSorted, oklch() colours, and "document.hasStorageAccess()". Note that some of functions described above are not actually re-implemented, just stubbed out enough to work. I would happily accept suggestions of which polyfills to use for each function. This fixes my issues with: - paypal login - immich - laravel docs - nest thermostat (home.nest.com) - autotrader.ca The required screenshot shows the nest webpage working in Chrome 109. Note that this extension is intended for Windows 7 Chrome 109 and older. I am unable to test on any newer version of Chrome, so use is at your own risk (and shouldn't be necessary in the first place).
