Download the zipped archive from GitHub Hovercard's GitHub repo. Microsoft Edge isn't accepting new extensions for now so it takes time to make the installation available directly from Windows Store. You can manually install the extension to try out.

Safari version is not available from Apple's Safari Extensions Gallery because Apple now requires the extension developers to purchase its Apple Developer Program ($99/year) to publish extensions. If you are a Safari user and you really like this extension, you can download the unpacked version and install it manually. If you are interested in putting it into the official gallery, you can make a donation here and once the donation is sufficient to cover the annual fee I'll get it done.

Extension version is not supported by your browser. You can try the userscript version. Or go to our GitHub issues for help.
