Not clear on how to make it work. Options menu never shows.

I will REPEAT what many others have said.....................

The old version let me do what I want to do, which is download the video and the extracted audio. It also REMEMBERS where I last saved a video/audio combination, so I don't have to keep traipsing around my hard drive to find the place to download.

WHY would you take a perfectly good program and break it so that it is only useful to complete tech-heads? It was fine before. It did what needed to be done. I have fiddled with this new version for about an hour now. I am done. GDit. I am so tired of having to go find alternate versions of things after the good version is broken by "improvements." What is wrong with "you people"?

The instructions say:
1. After installation, go to the options page and
-> 1. Install the native client (This is a small NodeJS client written by @andy_portmen)
-> 2. Install the FFmpeg executable
2. FFmpeg integration is required if high resolution video or audio files are preferred.
My questions are:
Where do I find the options page?
What is FFmpeg integration and how is it done?

The old version that was made by Inbasic is awesome. This is definitely garbage.
Saving option don't work. If you set right path to ffmpeg,that don't work.

I would actually give this add-on 10 stars, if it were the legacy version - the "old" one. But I was surprised with the notification of this one when I opened the browser this morning, and there was no Options page, no Button, and thank god I still had the other one installed. So, I tried the old one with a YT vid. song, and it worked beautifully. I disabled it, restarted my browser, and there still wasn't a button for this one, so it was useless to me. I checked to see if it was hiding in customization. Nothing. I used the legacy version 2-3 times a week, all the time, and never a problem one. It was perfect. I can see from the other reviews here, that I am one of MANY with the exact same problem. I do not know what to do now. I am using FF56. I hope this is resolved quickly. This whole transition has been a nightmare, and I need this. I'll probably end up going to Chrome like everyone else. Countless people are already packing their bags, as I write this. It is truly a shame. Thank you for a fantastic add-on - THE OLD ONE - though. I loved it.

Just as with the original, it is unclear from the configuration settings, what "you will get" upon choosing a download: a video-only file, an audio-only file, or a video with audio.

With the original, I know have it configured so that downloading a YouTube video delivers an mp4 video+audio and an mp3 audio-only. This is perfect, though I have not the foggiest which magical combination of unclearly worded settings gave me this wonder.

With the new WebFail version, I can not get the same result (video+sound, and audio). But worse, whatever setting I try, it downloads a video fail, then extracts an audio file, then deletes the video file under my eyes.

I downloaded and installed the extension. The instructions said to download an additional file from the options page. What options page? Where am I supposed to find it? There are no options given on the Firefox Add-on page. The old add-on worked great, this one doesn't work at all without an external file I can't seem to find. Also, I see lots of questions on this page, and no response whatsoever from the developer. So . . . the Add-on doesn't work and the developer doesn't respond. Why in the world would anyone want to deal with this nonsense?
