Lame. You can download almost no videos with the free version. Always need a (paying) companion. I forgot why a ditched it, now i remember...

I got an email from Mozilla regarding this extension

"Hello,

Thank you for your report about the following add-on on Mozilla Add-ons: Video DownloadHelper.

We reviewed your report and the content in question, and found that it violates Mozilla's policies, and have therefore requested the developer make changes. If they do not update their content to correct the violation, we will remove it."

One star for having to use a third party program to have to download, and then he pulled the rug on everyone and put a big QR code in the videos saying you have to buy it now, it's a scam.

Puts a huge QR Code on a downloaded video, asking for you to get a license. Use FOSS Software, not this repackaged junk.

This used to be a really good addon. It has become adware apparently with a big qr code added to any downloaded video. I however never got that far to notice since it crashes every tab that is showing a stream that is widevine drm protected after a while, even when you're not using it. When I found this addon to be the culprit I just uninstalled it. There are better alternatives.

This now adds a big fat QR code to all downloaded videos, because it wants you to pay for a converter. Just one problem: I didn't ask it to convert anything, just download. I've used this for years, but now I got a train ride ahead of me and all my videos are 20% QR code.

Absolute bait extension.
Donwloaded it, tried to use, asked for a third party program.
Then after installing the program, about 40% of the video it downloaded was a huge QRcode = video is half gone, want no QRcode? pay up, nah...
Ty no ty., I'd rather download the ocasional video manually.

one of most Fattest QR code known to man. i'll pass on this one champ.

Why is Mozilla allowing this bait and switch application here? You install the extension and then after a few working downloads it starts trying to get my to install a binary on my machine.

Freeware/adware as of 2025. Requires external companion app (CoApp) to download videos which itself injects a watermark with link to payment for removal. Ever since this change the extension rarely gets updated

Used to work just fine, but now it started to force you to donwload an entire additional app on your pc in order to download anything, even seconds long youtube videos

Complete scam. Super simple Firefox addon now tries to nickle-and-dime users by crippling the download functionality with a big honkin' QR code plastered across it. Steer clear of this one and get one of the others that are actually free.

Videos have a huge qr code watermark. It costs $30.50 to remove it. Other websites can do it free.

Giant QR code on "FREE" extension is not so good idea

Ah yes, a free tool now slapping a giant QR-Code onto your video. It's not like there's hundreds of alternatives that do the exact same thing this simple add-on does.

scam

Watermark? Nope, one star

Rendered itself completely unusable forcing QR codes into all videos asking for a 20€ donation for a license. Uninstalled.
