Where should I put this script?

@developerfromjokela TaperMonkey (Chrome) or GreaseMonkey (Firefox).

I'm getting a error. When there is an ad about to start, the music keep in play pause the whole ad duration. The only thing I could do to stop was refresh the page.

It stopped working after few weeks :(

it's stop working after few days, how to resolve this? ty

@rikapinka @Weridox

I've updated the script. It now detects ads and mutes until the ad is finished. It's not as clean as previous technique but it does the job for me.

doesnt work anymore

@marcbelmont does it skip ads?

@marcbelmont does it skip ads?

@dayoshiguy It mutes the ads. Good enough for me.

@marcbelmont
Thank you for your work. I use updated script. Works fine for me.

tysm !!

How to use this script? I did run in the console, but it isn't still working.

You should use something like violentmonkey to install this script.

This handy inject function, is that part of a library somewhere?

Works perfectly! I don't have much BAT but here's a tip @simonwep

Great work, thankyou.

Why don't you publish this on Greasy Fork?
