It places a huge QR code in the video.

Used to be a great extension. Now it doesn't work that good anymore.

I have tried several times to download this add on, and it will not download to my computer. I can not find the icon.

Ho scaricato la licenza a pagamento, dopo alcuni giorni ha smesso di funzionare, facendo alcune prove per vedere di sistemare il problema mi è stata bloccata la licenza anche. Ho scritto mail a support nessuna risposta.

worked fine for awhile now can't get a video downladed.

La aplicación te obliga a instalar un "software auxiliar" (no funciona sin este) que el antivirus detecta como malicioso y dañino, cabe señalar que utilizo macOS 10.12

One star (less is impossible) because it is impossible to choose every time the folder where save the file to download.

Been using this for years. Excellent addon, but I'm not going to pay for something that I can do for free. Uninstalled as soon as I saw the new (huge) watermark in the the top left corner.

Does nothing and requires to install some binary. Not something i expected.

I got ransomeware from this, so be warned.

I was on Youtube, trying to download a Kingdom Hearts cutscene video, and whilst it was downloading the 1080p version (which uses the companion app), my anti-virus started popping up messages saying "Threat detected, no action required". At first only 1-2 ever 10 seconds, than about 1 every second, until it finished downloading the video.

Once done, I navigated to the folder where the video was downloaded, and all of a sudden ALL the files in the folder turned into "DOCM" files and a text file appeared giving me instructions on how to retrieve my files by sending money through TOR using crypto currency.

I checked 3 other folders, wherein all files turned into DOCM files, and then immediately shut off the computer. I had to completely reformat C Drive, and reinstall Windows and everything from scratch to kill the ransomeware.

Thankfully most of my files which were not on C drive were saved due to shutting the PC of quickly, but just BE AWARE! I was not doing anything whilst downloading the Kingdom Hearts cutscene video. I was not browsing another site, and I was not downloading anything else.

So the companion app for this add-on more than likely contains ransomeware!

Total crap, even 1 star is too much! All it does is saying "companion application required". Forcing me to install some app? That's sure NOT what I expected! Most of one-line reviews here are fakes...

I installed this add-on because of the great reviews. Little did I know that it takes 15-20 minutes to 'download' a 4 minute 1080P video from youtube. The extra time is the combining of files (aggregation). After it does its aggregation you get a WATERMARK in the combined video, RUINING the entire thing! The developers say that you want to remove this watermark either don't choose the ADP option when you download or PAY them. Surprise surprise, the MAJORITY of HD videos on YOUTUBE have this ADP next icon to them. In other words, if you want download in HD you HAVE to choose the ADP version of the video. RIP-OFF! Did you guys PAY peeps for the 5 stars reviews or what?

Edit: Ok maybe was a little harsh in my review but this add-on works on other websites where the videos do not need to be combined together. Still your business model is flawed in this day/age. There are plenty of other (free) video download options out there which do not force users to do things they don't want.

Used to be a very helpful program. Very difficult to get it to stop throwing a barcode on top of videos now. I have upgraded to J dnowloader. This was a must have and is now a must skip.

Junk. It doesn't work.
