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

It had been a really useful extension. But from the day I updated to FF 76.0.1 on, It's not working at all. Please fix this issue, since some depend hugely on this. Never thought, I'd have to rate this with 1 star since it worked absolutely fine.
===================Updated Review============================
Thank you dev team for the new update provided. Glad to see Add-on is back in action. Deserved 5 Star rating is given back.

Edit: it is working fine with Firefox 76.0.1
thanks for the reply
