Initially there were some problems which were attended to quite fast when reported. The add-on is working fine now.

Update 2022-08-29 FUNKTIONIERT IMMER NOCH GEIL! Ich kann Euch die PRO-Version nur empfehlen.
2021-01-05 Ich benutze das Addon schon recht lange, habe mich nun dazu durchgerungen für 15$ die PRO-Version zu kaufen um auch 1080p-Videos von IRON MAIDEN runterladen zu können. Ich kann Euch versprechen: Das Ding ist jeden Cent wert! Innerhalb von ca. 30 Sekunden war ein 13-Minuten-Song (Red&Black) mit 350MB auf der Festplatte gespeichert! HAMMER! Das Freischalten geht durch die E-Mail-Adresse ganz einfach und innerhalb weniger Minuten. Unterstützt die Entwickler bitte und kauft ebenfalls die Pro-Version. Ich verspreche Euch: Ihr werdet es nicht bereuen.

Great app, especially after the update that fix the download.

Simples e eficiente. A cada dia fica melhor.

Excellent add-on and superior customer service, thank you Dishita!!!

Makes downloading YouTube videos so easy.....and no waiting for stupid ads!

Very useful for downloading HD, as Youtube and Firefox make changes the App is updated quickly.

awesome

Love this easy to use add on for you tube clips removing ads and making it perfect for young children, so no unfiltered ads pop up.
Recommended to all my friends already.

Works on Firefox / Yandex in windows xp / 7 and 10 , also on my linux mint.

Does what it says. Hopefully will keep updating as and when required.

This is a brilliant add-on and well maintained. thank you

Does what it says and responsive support!

Doing a great job keeping the extension functional while Google/YouTube try to break it! Support this developer!

This add-on is one of the few reasons why I use Firefox.

For whatever reason lost the usage of another Youtube downloading extension that was fast and easy. Thankfully, found an equally fast (if not faster in only seconds for a 200+ MB file) downloading with similar format (same drop-down menu links) in your add-on. What a relief!

A VERY HANDY TOOL! THANK YOU VERY MUCH DISHITA!

Great dev, great software -- Almost always one of the first to update after ZooTube purposely cripples these types of software on the regular.

A++
