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.

Used to work great, now I get errors from Firefox that this script in particular is slowing down the page. I have to temporarily disable it to watch a video or even get a channel's homepage to YouTube to load. It even does this if I have the side panel closed. I have 564 subscriptions and I am using a 64-bit version of Firefox on Windows 10 Professional. Not sure what's going on beyond that. Very sad, though.

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.

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?
