Seems to be working without issue, however I only give this addon 3 out of 5 as it seems to be limited to downloading a maximum of 720p, even if the video is 1080p or higher. Even the settings shows a maximum of 720p.
I also have "video download helper" installed, which allows any quality to be downloaded, depending on the video source itself, but this addon only allows up to 720p, and I have no idea why. There doesn't seem to be any "pro" version or a version which you can pay for to get access to higher qualities.

It could be the greatest extension. The most slick and powerful. The problem is: videos from FB are downloaded without audio.... So basically at the moment it is completely useless.

This is the greatest for YouTube downloading

this is awesome

download video from facebook.. video quality 720 is clear but no sound! what's happening here? im using firefox version 77.0.1

THIS IS THE EASIEST TOOL ANY ONE CAN USE, TAKES YOU TO EXACTLY WHERE YOU WANT IT TO GO SO SIMPLY

Video downloader

wow this worked for me!
i tried to download videos from dailymotion and this is the only thing worked

I have FF76.0.1 and the latest version of the addon 1.0.9.86 and I still get the blank dropdown, i have removed completely and reinstalled and it stil wont work:O(

Great! It's working again!

The addon works again in 76.x! Yipiee!

This used to be my fav dl'er but as others have already said, it quit working after the ffox update. I can't give something 5 stars if it doesn't work, right?
I understand if you're not very motivated to work on a fix, as it was scheduled to stop working w/in 6 months or so anyway. I'll miss it. Thanks for many happy dl's.
I won't delete it yet, in case you might fix it. My rating will change to a well deserved 5 stars then.

EDIT: Excellent! It's back! Thank you---back to a well deserved 5 stars!

Depois da atualização 76.0.1 a extensão parou. Ainda assim, deixo 5 estrelas pq acredito q irão corrigir o problema. Essa extensão é d grande utilidade
