The integration of this video downloader with the browser means it can identify video files present via a web page, including in various resolutions, and allow you to select which one to download for local archival. The developer has always been very responsive when sites change things that then interfere with this plugin - and once he figures out what's changed (that can take a bit of time), the update is posted rapidly. E.g. the latest update fixed problems created by an unannounced change at YT. Best and most stable downloader I've ever used. Thank you.
