This used to be a great way to download video but lately it updates about every day and then after the update it won't work. Weird thing is that it started doing this after Firefox's latest update, and sometimes when I first try to download it works, then it automatically updates and won't work, claiming I need to download some stupid companion app which I don't want to do because I"m afraid something else will be downloaded along with it (malware, spyware). It was great the way it was!! WHY did they have to screw it up???!!! Have they ever heard the expression "if it ain't broke, don't fix it"??? Looks like either they're just making up an excuse to try to get people to hand over money for a paid version, or Firefox really doesn't want us using this tool. Either way they're just pissing people off, and they'll quit using both the add-on AND the browser if they haven't already.
