Doesn't actually download video. Instead it prompts you to install malware.

Does not work out of the box, REQUIRES MONEY TO WORK. how the fuck does firefox recomend this bullshit?!!?

Требуется установка стороннего софта и оплата премиума.

SCAM! Ask to install some software

addon has to gone to shit. it now requires aggregating videos, a license, overlays a qr code on your videos if you dont pay, dont both with this. id give negative stars if i could

On my system (Debian) the helper app frequently stalls and there doesn't seem to be a way to kick it.

I also have another problem with the author(s): I frequent a (for-pay) web site on which this add-on didn't work. The author rejected my offer to use my account for testing. OK, I can live with that, so I found a free video which exhibits the problem and added a comment with the link. That comment was deleted from the forum, without notifying me. So was a follow-up message asking for an explanation. (Politely, I should add.)

Sorry, but this is not acceptable.

Não funciona em nenhuma hipotese, baixei o gerenciador interno e ainda assim não funcionou.

essentially a paid addon - demands ~20 dollars to do it's job.

Ich bin genervt, nur noch genervt. Mal funktioniert der Scheiß, dann wieder nicht. Und ich habe keine Zeit mich ständig mit den "Neuerungen" eurer Drecksprogramme zu beschäftigen, die immer wieder das Nicht-Funktionieren nach sich ziehen. Nieder mit IT. Braucht wirklich kein Mensch, wenn es nicht funktioniert. Lasst doch einfach eure Scheißgriffel von funktionierenden Programmen! Wie psychoneurotisch sind eigentlich Programmierer? Das Scheißteil will nur noch von UTube runterladen, wenn ich die Begleitanwendung installiert habe. MP4 findet es schon gar nicht mehr. Für alles wir die Begleitanwendung gebraucht. Dann könnt ihr die doch gleich integrieren, wenn's ohne nicht geht. Ich hab's echt satt, ständig für all die Programme meine Lebenszeit dafür zu opfern, dass der Scheißdreck wieder funktioniert. Ich hab auch was anderes zu tun und keinen Bock ständig vor den Kisten zu sitzen und mich den durch sie entstehenden Problemen zu befassen. Fuck up

Watermark is a NO NO!

Leider funktioniert der Downloadhelper fast gar nicht mehr. Ich wünsche mir ein auf die neueste Version von Firefox aktualisiertes Unplug.

Puts a large watermark on the screen and demands payment to have it removed.

This extension is the worst piece of s**t I've ever seen. I made an account and signed into it just to make this review. Not only does it NOT WORK, but it requires this massive privacy-invading add-on that's 40 MB and is mandatory to use it. Then, once you have that downloaded, it fails to recognize any video, and in the 1 in 20 chance it does, takes forever to download it, assuming it actually downloads it correctly. All these 4 and 5 star reviews are COMPLETE LIES! This extension is utter dogs**t! I wrote this review just to warn people not to use this crap. Not to waste their time on it, and not to download that massive bulls**t "companion" add-on that's required. I've never hated a free browser extension more than I hate this utter trash that has wasted countless minutes of my life.

Not sure why but when I tried to download a video from facebook it used 100% of my CPU, and I have an intel core i9 9900k, not sure why it needed so much power.

Avoid. Incredibly slow thanks to "aggregation" after the (already slow) download process, adds a massive QR code to any video downloaded that can only be removed with the nearly 30-dollar paid license, requires the installation of an external program for no clear reason and the extensive permissions requested seem suspect.
