Outdated extension. Use uBlock Origin instead to block ads without blocking your music:
https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/

wont get rid of ads
keep getting the message

good enough but sometimes screws up for whatever reason

blocks the ads... but stops playing music

The extensions work but,
You get the Oops message whenever you reload and you may not have ads but sometimes the music pause abd you either have to reload the page or skip to the next music hoping it works...
Hoped there is a public repo.

Edit: doesn't work anymore, changed to 1/1

Whenever I click on a song, it skips that song plus like, 5 other songs and I end up listening to a completely different song in that playlist/section. Also, ads still play but on the web it shows a song being played. No idea what's happening here. I think your code is working a bit backwards here lol

Used to work but now no longer does. Get a 502 gateway error instead of the web player. Shame, it was the only extension that actually blocked the ads instead of muted them.

doesn't work. Reloading the page just causes an error message to pop up on the page.

Works, but always displays the "unable to block ads" popup, even though it always works, which is really annoying
