''duplicate of https://support.mozilla.org/en-US/questions/983862 - locking'' I download this addon "Magic Player" but did not install it: http://magicplayer.torrentstream.org/index.php?lang=en# How can I find the folder where the install package was down loaded so I can delete it. I have looked every where "history" "library" "cache" and "download" folders but do not find it. Where does the addon file download if I did not click install after it downloaded Yours sincerely, Christophe Smith
