free version doesnt download anything at all, wasted three minutes of my time

Only a tease and doesn't work unless you pay $10 for pro version.

Free version is just as a tease, to lure people to check it. Doesnt work. Everything requires payment.

It's stopping youtube videos after 1-3seconds runtime in Firefox right now.

this is scam, extension should be removed from the site.

You must donate to use this addon, piece of shit

Tut nicht im mindesten, was es soll, trackt mich gleichzeitig, soweit es nur kann. Nicht zu empfehlen, sehr unseriös.

Do not use addon. It is a scam. I donated to get the pro version and it worked for a little bit then stopped. Tried contacting the author multiple times with no response. It seems like the app is a bait and switch, works long enough til you can't refund the donation then stops. Beware.

You need to be a PRO member or some sort to enjoy the services. Trash.

Garbage dev. Every year he finds an excuse to make you repay for it to work properly. He has enough of my money. Reporting for abuse. I suggest that the rest of you do the same. He needs to be held accountable. There are other extensions that working properly and for FREE at the Chrome store. No need to use Firefox any more since it's just a Chrome clone now.

Over half their features are 'pro only' and they point blame at YouTube.

The description only reveals in the last paragraph that for the high quality downloads, you have to pay for the PRO version. I did that, but less than a year later than are trying to change the terms of the agreement and switch it to a subscription based system. They have deactivated my PRO capabilities and though they claimed they would reactivate my PRO capabilities or refund me, they have refused to do either despite my 6 repeated requests to them. These owners are not living up to their commitments and are bring shame to themselves, their families and their product.
Their continued lack of communication leads any rational person to distrust and suspect the nefarious intentions of the owners. STAY AWAY FROM THIS APP.

I am simple mind user.
I am a veteran with some technical knowledge.
I am in no favor of any partisan whatsoever.
I am used to be able to just enjoy add-on(s) and the things those wonderful developer worked so hard to share with others.
This add-on is not one of them.
I do understand no one wants to work for free in such a hard time as whoever you & your god knows it.
So, it would only be acceptable courtesy to just mention right upfront that your add-on is not to use for free.
I am sure I am clear on the issue to everybody who cares to read.
Also, I do not do well to respond with people whose illiterate tendency had heavily influenced their communication pattern. Neither are also applicable to those overwhelm with ambiguity and those with complex transfiguration.
