I love this extension, it does what it says and finally makes having more than 20-ish subscriptions viable by splitting subscriptions into customized categories. Finally for firefox!

upd: Great addon <3

Wiorks Perfectly.

Thank you very much for your hard work!

Really great way to organize your YouTube subcriptions. The extension existed for Chrome for a long time, really happy it came to FF.

It works again!

Спасибо, отличное расширение, лучшее в своем роде.

Fantastic and amazing extension that anyone who loves to watch YouTube absolutely needs. I'm honestly surprised YouTube hasn't implemented this already but it is a major time saver when sifting through hundreds of channels and trying to find the kinda thing you're feeling that day.

Really missed this feature on YouTube, and more then happy to see it come back with this extension.

Essential.

Great extension!! Thanks

Absolutely fantastic! I've been waiting for this to be ported over from Chrome for a while, and it's finally here!

A great add-on that will finally bring order within your 500 subscriptions through the power of folder structures. Works fine and is was I just what I was looking for. I still have no idea why youtube disgarded this important feature in the first place ...

it changed my whole youtube experience, perfect!!
