Where is the Download? Can't find it on my computer any where and I've checked the site to see which folder it is in.

This extension is a lousy impertinence. A video can only be 30 minutes long, which is converted to an MP3 file. This is absolutely ridiculous. As long as this does not change, I will not withdraw my one-star rating and tell all my friends and acquaintances not to install this extension. I will also uninstall this garbage extension. I quite rightly expect a YouTube to MP3 downloader to be able to convert videos that are longer than 30 minutes.

So far, just tried it, and it works. Thanks for this add-on!
