## Description

osu! Beatmap Preview lets you preview osu!standard beatmaps directly from your browser.
Open an osu! beatmap page, click the extension icon, and view an interactive canvas preview of the map without leaving the page. The popup reads the current osu! beatmap URL, loads the beatmap file from <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/dab3fd6368683a2c1d8aa135d81312eea2ceb0e5488552f2944e4d9c46bb2a0c/http%3A//osu.ppy.sh" rel="nofollow">osu.ppy.sh</a>, and renders the hit objects with playback controls, difficulty details, and mod selection.
