No answer from support. Paid to have better service without any change.
A TRASH that don't merit even one star...

It doesn't work

Nur 1 Download innerhalb 24 std !!!!!

Was good for downloading the audio component of a video. It's no longer free. They're pushing the 'Pro' version which requires $s...

Misleading description - MP3 not work with free version.

Useless, has only one link for youtube video, and no audio links. Commercial, advertising. Needs 3rd party server. Better is youtube-downloader-lite which has direct links to audio only, video only, video, without 3rd party server. Can't belive this is recommended extension.

Bought the pro version for $30. I cannot download to mp3 or 720 mp4; forever stuck in "job in queue" or "working". I have waited an hour, and downloads in these formats never even begin. Do NOT give your money.

Like other top-rated addons in this genre, you cannot download YouTube videos in an MP3 format without paying money.

It is NOT free for all downloads.

Installed.
Tried to download some video as mp3.
YOU MUST BE A PRO USER.
Uninstalled.

Terrible UI, sketchy website, and requires payment to download at 1080p. Giving your payment information to this scam of an add-on is basically begging to be robbed.

Worked for awhile but then it just stopped. Was instructed to wait till the issue could be fixed... now it is supposed to work, but it still doesn't... waste of time & $$

the author got greedy...no longer able to download mp3 unless u donate

This is a switch bait scheme. You won't be able to download in proper HD formats unless you cough up some cash first. They explain how you "need powerful server infrastructure" to actually download in HD and how it's "limited to PRO users only". There are literally TONS of other Firefox addons that do the same job better, and for free. My suggestion to the developers is to find a real job. Makes you wonder why Mozilla is recommending this addon.

Does not work at all.
