Versions 1.0.8 and later of this add-on will not work properly with older versions of Firefox. If possible, please return to the specifications that work with old Firefox.

Works great for downloads but it stopped joining audio and video for youtube videos a long time ago and it hasn't been fixed since. There are a few workarounds that are all a total pain.

Firefox 48 and 52 - does not work
Mobile Youtube - error

It offers mostly video-only or audio-only, 360p an 720p almost useless

Downloads alright.
Conversions keep failing, despite numerous installations of ffmpeg.exe and ffmpeg-win32-ia32.exe in Roaming folder, (and different other locations). I changed path after each change. No luck. App used to work. Windows´ updates & re-installs seem to have a negative impact on the app. Do I need to buy a new laptop with a clean Windows install & clean app install just to get this app working? Seems exaggerated to me. I´ll look for another app.

Cannot download 1080p.

Worked fine until a change was made on 06/01/2020. Now nothing is downloaded when I click on the "Quick Download" option.

all download interrupted because file downloaded for audio and video have same name and extension.

It won't combine both the video & audio for vids DL'd via YT, & I have the latest FFMpeg installed too! & it is all config'd properly but yet will NOT combine both when DL'ing, & when I try & combine them afterwards in Media Muxer & Converter, it gives an error msg everytime I try & add the audio file to the video combiner. This addon USED to work just fine, flawlessly, even. Now it won't do what it's intended to do! & I recently formatted my SSD, & reinstalled EVERYTHING, so, very doubtful of any corruption. & I have a very good Internet Security suite installed & config'd properly too. So, WTF is the problem?

oof cant get it to work oofing bad

Okay, so I enabled Post processing (if FFmpeg is installed-it is) convert to MP3... it doesn't do that. Which is why I wonder if it's right to have "-loglevel error -i %input -q:a 0 %output" in the MP3-conversion field or if there's something else I have to change.

Sorry, but not very useful as it only presents a limited range of resolutions that are video & audio and theyre all either too low (360p) or too igh (720p+). Im used to being able to get 480p (perfect for me on limited data and mobile) which i usualyl get via IDM...currently im in Linux and if course no easy IDM downloads, so trying all Add Ons for youtube. And so far, all are so limited....this one is just weird, theres 1 page with limited video&ausio options and 2 pages of audio or video only options...bonkers....

Seems to work sometimes. Not terribly bad.

Used to work great. Now it says "YouTube Video and Audio Downloader info.title is undefined" Anyone else seeing this or have any solutions?

No 4K or HD

720p and 1080p don't work

does not work, "signatureLocal" message etc. Being logged in changes nothing.

Cannot Save to MP3 (for playing in my 2010 truck)!
