I waited patiently and saw some good reviews and some not so good. That's to be expected but I waited for an update (initial releases can be twitchy especially with the new FF) and finally tried it for myself. I use it on select sites and though it's not quite what it used to be, it works for me for what I need. I can't speak for downloading everything from every site out there but for what I use it for (video from a few sites only), it works with no issues. I even tried it first without any companion app and for my needs I'm satisfied with the operation of it. I don't really care that I can't pick the download folder. It downloads. Really, what more do you people want? Do you not know how to move files after download? The addon works! I know it's been an effort from the developer to get this going and I appreciate the hard work. I've only had this installed for one day but so far it's worked without any issue. Maybe I'll get to some sites where it will falter but these are still early days and the developer will always work to further the cause but for now it seems to be working well. Thank you.
