BAD Add-on. Doesn't work, period. Go to their site and they'll ask you to pay for the most basic version. They are using Firefox for free advertising.. at least, or maybe it's something more sinister, considering that everything is in German.

Oky

Every video you try to download with this POS addon "cannot be found", explanation of why is in German and requires you to use Google Translate. And it's just a poor excuse addon. It's probably just a back door for hackers or something.

Most time not working!

Bait and switch for video downloader ultimate which I assume is some paid BS. Doesn't work with youtube, says the download link is incomplete. The only way that could be true is A they are too dumb to code, or B they aren't but want you to switch to paid product and this is how they do it. You deserve no stars.

Doesn't work.

I'm tired to spent time trying one by one extension to DL video they don't works! If you no support Android write it! Blame even on Mozilla because don't put entry "Android" in s.o. supported pulldown menu.

Downloads fine, but NO SOUND. When I tried to get through to tech support, VideoDownloaderUltimate says Private Video Downloader is not a product of theirs!?!?!

the add on simply doesn't work. I can't get a video download from any source. Has no business being a plugin on Mozilla

Ten out of..eh.... 1 septillion?..Yes, that's the correct rating haha!

Absolute DUMBEST addon ever, wow!
- soooo private, that when you are in a privatemode, it still does the download to your regular window
and puts it nicely in the download history

- which brings me to the other genius element, you have to STORE manually EVERY single site
in the addon's setting...to enable the private function of it automatically deleting the history

- there's no working option to manually choose where to save (the check box unchecks itself when you reload
the settings page

What a troll this developer.
Amazing there are even people rating this higher than 1 star..

Не понял,как оно работает? Значок появился-но при нажатии ничего не происходит, к тому же запрашивает чтение персональных данных,зачем-то? УДАЛИЛ! ХРЕНЬ!!!

Never recognises videos

This is almost a scam to try to get users to upgrade to a paid version. Why?

Tried it on youtube and nothing downloaded.

didn't work. when i clicked on "why" it was unreadable (not english"). huh?

Heb nog niet gebruikt
