Devs tell users that "Converting these streams to downloadable formats for you needs powerful server infrastructure, therefore 1080p/mp3 downloading has been limited to PRO users".
That's absolutely not true. It's done instantly by any free video encoder. So don't lie to you users.

They charge money for HD also i only tried this because my other downloader kept failing but this wasn't able to do the job either. So, i might as well stick with the broken one that doesn't beg for money.

Garbage. Its not downloading MP3 or HD unless you pay for it.

fonctionne pas. faut payer.....

Its useless.

I had 15.2 and it had that waiting forever error and crated 0 byte files. went ot update to 15.3 and it installed 14.4 instead...whats up?

always breaks and asks for donations to upgrade to Pro eventho it has been done several times.

it dosent work anymore

Doesn't do as advertised. Doesn't work with Youtube's new bullshit. The only way this works is if you have your own video editing software and download the video and mp3 separately and then manually combine and render them.

This simply does not work. When you try to download something from Youtube, the extension give you a longwinded excuse why it doesn't work. Don't bother.

Total garbage. When Firefox does an upgrade this doesn't work anymore until you 'buy' again. Support has become useless (even after buying twice to be a nice person). Save your money.

doesnt work

Garbage.
Absolute garbage.
I donated once and it worked fine for a while and then stopped working.
So I donated again and it worked fine for a while and then once again quit working.
This was both times with the receipt page open in another tab.
Don't waste your time and money donating for the "pro" version because it's garbage.

And once again it's decided it doesn't want to work.
Just plain junk.

If you want to download anyiting in 720 or 1080p you have to pay at lest 10$. It should have be written in the major description, I don't like this kind of clickbait.

Does not work no download button is displayed at all.

I have downloaded and uninstalled this add on 3 times and cannot get to 1st base with it simply because I can't find it. It says it is there when I check the add on page. But that is as far as it goes. Half a Star.

Originally gave this 5 stars, dropped to one because I paid for pro in 2019, now I have to pay again because he changed the auth system??? Sorry, no.

New fix just posted 6/19/19. Will update my review once I have a chance to test it.

Now: Stopped working ... response to my question did not solve the problem.

Earlier: The add-on does everything it claims to do. It's simple to use and works flawlessly - I heartily recommend it and I too have donated more than once to support the developer.
