Does not work and requires you to install companion app. After installing companion app still does not work...

Don't work on firefox snap ubuntu 22.04!!!
"Companion application not installed", but installed.
I can't find an older version of firefox, where can I find it? If I find it (.deb), will it work even though I have installed the snap version???

"Companion application required" but I already have the app installed.

Funktioniert leider nicht mehr. Die zusätzliche Software, die man dafür benötigt, lässt sich unter Windows zwar intallieren, wird aber vom Add-on nicht erkannt. Es kommt nur noch die Fehlermeldung: Prüfen der Begleitanwendung ergab: An unexpected error occurred.
Ohne diese Begleitanwendung ist das Add-on leider nutzlos. Support gibt es keinen. Das Support-Forum unter Google Groups ist von Google gesperrt mit dem Hinweis: Die Gruppe "Video DownloadHelper Q&A" enthält anscheinend Spam, Malware oder andere schädliche Inhalte.

Le test de l'appli compagnon a retourné: An unexpected error occurred

War mal eine gute Erweiterung. Seit neuestem wird nach einer "Begleitanwendung" gefragt. Installiert man sie, wird dennoch jedes mal aufs neue nach einer Begleitanwendung gefragt. Nutzlos geworden. Schade. Installation für Ubuntu lohnt nicht.

No instructions or explanations. Don't know where my downloads are. No instructions on how to direct, retrieve or use any video you downloaded with VDH. Waste of time, no use on using if cant retrieve your videos.

Funktioniert nicht mehr. Habe keine Seite gefunden, auf der der Downloader nicht eine externe Anwendung (vermutlich Spyware) benötigt hätte.

Installed the extension, added the helper app, and no matter what I did the resultant files were unplayable. Literally in VLC player nothing would happen. The file would have a 0:00 time length. No errors, just an unplayable file.

The Add-on does not work for me anymore, at least on Youtube. I have deleted cookies and history cache, reinstalled Firefox, reinstalled the add-on. This did not help. Something is broken. It starts downloading, then indicator turns red, showing the error that it can not extract data from some tmp file. The error appears regadless of the video resolution. Too bad. Other video downloading add-ons work fine.

I understand that You need funds to develop add on. I can agree with qr code hardly . But two things: converter changes resolution, quality and smoothnes of downloaded videos; QR is much to big. My opinion is that You are going to loost users neighter got money.

Does not work properly anymore. Checking License and CoApp just hangs on Infinity Loop, does not register most sites which it did couple months ago. I do not recommend to buy a licenses until it gets a Update.

This extension used to be great, unfortunately has become unusable now. The downloaded videos have inferior resolution compared to the original videos. Further, there is a large QR code appears in the top left for the free version, which renders the entire download useless. There are plenty of extensions which are better when it comes to quality AND free

Doesn't work with flatpak or snap version of firefox but videodownloaderultimate does (not as well but does work) until they fix video downloadhelper. Maybe the developers should look at the code of videodownloaderultimate
