version 0.2 only work on new layout, if you still have old layout, use 0.1 version of script

I was going to post this patch for the new UI but looks like @TheBSODAndWSODFan already made a new script. I went with a different selector, but essentially does the same thing

None of these are working for me any more and I'm seeing the message "volumeSlider not found" in the console log. Could someone help me out. Thanks

@tigre7575 my version of the script still seems to work, you can give that a try and see if it works for you.

My fork: https://gist.github.com/fa7ad/fa995474f5cb9fe91fb209686881373d

@fa7ad Thanks for the reply. After testing out your version I figured out that this seems to be an issue with Firefox and Youtube most likely, as these scripts still work in Chrome but not in Firefox.

Weird, I'm on Firefox as well. Maybe its the extension you are using to run userscripts? I'm using Violentmonkey, might be worth a shot if you still want to use Firefox

Thanks for sharing that. I created a new blank profile and it works, so my FF profile is just broken which I've seen before.
