pourquoi mozilla ne laisse pas ce module s'installer apres mise a jouur?

이 어플은 가장 즐겨 사용하고 있습니다.

가장 좋은 어플입니다.애용합니다

it's not working anymore... Error: "signatureLocal: Signature cannot be verified". Please fix it.

Замечательно!Советую всем.

Tried several youtube addons, however this one, kicks preverbial ass

Really good, I can download some brief music videos to use for meditation! Thanks :)

比什么VDH好用多了，完整下载，同时还下载了音轨。非常给力

Yet again a new Firefox (66.0.2) update has messed this downloader up hence the signatureLocal: Signature cannot be verified message. This downloader also hasn't been updated for seven months so that probably adds to the problem - when working it's a five star extension.
