Hi, adwcleaner say that this firefox extension {b9acf540-acba-11e1-8ccb-001fd0e08bd4}.xpi
is Ad/Malware, but it is the orginal "Easy Youtube Video Downloader Express 9.02" from Addons Mozilla.org
https://addons.mozilla.org/de/firefox/addon/easy-youtube-video-download/
So i think it is false positive. Please fix it. Thanks
