Get AlwaysShowZoom on the Chrome Web Store
This has been outstanding for years as tracked at the following pages:
- Chrome Zoom Icon always visible - Google Chrome Community
- Always show Zoom button | Microsoft Community Hub
To keep the button from disappearing, this extension tweaks the zoom by an almost imperceptible 0.1% when it is at the default level. There is one side effect when repeatedly resetting (ctrl-0) where it will toggle between the default and the next increased zoom level.
For a button to zoom in with a single click, pin the extension in the toolbar.
This extension does NOT collect, store, or transmit any user or usage data.
