I&#x27;d have to look at the code but you can detect just about anything within the browser; do the check once regarding what features you want to use, store and do that. User agent string parsing is a hack that&#x27;s typically easier to do hence why so many still rely on it.<p>Having said that I don&#x27;t think they&#x27;d be all ears; their code isn&#x27;t opened source and while I could try to debug through their minified code that hardly seems worth it for me to do.
