갑자기 QR Code.. 안 써.

Does what it should, but ADP-based video sites (YouTube etc.) require a conversion with this app. When doing so, it gets stuck on a lengthy "aggregating" process, wherein it is applying a watermark to the entire video. This process is throttled and takes ages (over an hour for a <5 minute download.)

Paying a whopping $30 USD for a license skips this step completely. Which is to say it's completely unnecessary, and exists just to twist your arm for cash. No thanks.

I've used this add-on for a long time, but more recently it seems any video (and I mean any video) adds a watermark upon download, and apparently the only way to avoid this is to register and pay them. Maybe I'm using it incorrectly, but I'm disabling it now.

Way too much of this add-on requires an external application or redirect. That's ridiculous that even the "quick download" (the most basic function this add-on exists for!) requires it. I see this hasn't improved at all since the last time I'd had it installed years ago.

It seems to be quite nice at first glimpse, but, the "aggregation" puts a big (really big) QR-code to the upper left corner of the downloaded videos, in order to force you register (==buy). And does it causing a huge load to the CPU/RAM/GPU for minutes or quarters of hours(!). And several cases this "aggregation" is the only option - despite, what is written in the description.

Not really fast, and need to pay to avoid a huge QR code on the screen..... Bad!

Maybe it's just me but I found it all to complicated, I saw talk of $ for a license, then there was all these permissions and here at the end I see that is made outside North America. I just don't feel right about it so I am deleting it. I may be wrong about all this but it just doesn't feel right.

why i cant downloads

Video DownloadHelper Companion App 1.3.0 doesn't work with Firefox 72.02 (Mac OS X Sierra 10.12.6)

This does not work the same since the last FF update

This app was awesome for years but has not kept up with the times. I'm running latest version but it no longer detects YouTube videos in an MP4 format. You now get a horrible watermark and the quality of the conversion is severely degraded.

In the past, this has been a useful and dynamic add-on. It has now been monetized (watermark/stamp on downloaded videos) and requires installation of an external application that is not the git-hub secured version. The "companion app" is basically just FFMPEG, which many have installed by official sources but this official one is not recognized by the add-on. This leads to unnecessary and risky additional apps. Sadly, there are no brave alternatives for websites besides YouTube, Vimeo, etc.
