For about 1 year+, this add-on has not worked. When attempting to convert musics to mp3, the error message displays that the site cannot be reached (or, "Site is down") - with one of the letters in the www.ytmp3eu.com changing to ww1.ytmp3eu.com (or, .net, or .eu - depending on when they change the site suffixes). If the developers don't want to fix it, nor want [public] traffic on their site, or simply no longer in business - then REMOVE the damn addon! It's simply taking up internet space. Out of site, out of mind.

Watch, a troll or probably one of these ytmp3eu-scam artist is going to try to bump this non-functioning, spam add-on with a 5-star - claiming it works & it's a good app, when observable reality proves otherwise.
