Is Postlight Reader - any website safe?

Medium risk

Postlight Reader uses remote rules to place full-page browser-download overlays on popular websites.

After page load, the extension fetches a remote config from postlightreader.vercel.app and matches rules against the current site hostname. For enabled sites, it builds a 100% width and height overlay with no dismiss option, text saying the browser is not supported, and a download button that links to thebestbrowser.shop.
