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.

I've been following this addon since it was on chrome and even considered switching, but finally the firefox version appeared late during 2017. Unfortunately i have the same issue as the previous reviewer, the subscription manager section loads infinitely. I included a video here. https://youtu.be/a2omrEc_I_o

My main browser is cyberfox 52 but i checked on various firefox versions. I never got it to work on multiple versions from 52 to 56 but it works on 57. Sadly i can't use firefox 57 due to many plugins i use for school and work not being available with the new system. However, this addon claims to work on firefox 45 and up.

One thing i noticed while writing this post is that all versions i tried are 64-bit, maybe it's a 64 bit bug? i'll be trying when i can a 32 bit install but in the meantime this is the bug the other user mentioned.

In short: Doesn't work on firefox prior to 57 despite claiming to work on 45 (all 64 bit versions).

Edit: Thanks for your quick answer. Saw you promptly changed the version requirements. I hope i can try it out eventually.

The subscription groups bar keeps loading and cannot function at all, how home?

Provides essential functionality; overcomes Google's shortsightedness.

Essential.

Requires permission to access all websites. Sends tracking data to "mixpanel.com"

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!!

Excellent and very timely addition. Thank you!
