Works like a charm. Can be used in conjunction with an skippable ad auto skipper to remove most of the annoyance while still supporting Youtube creators.

Wanted something simple to run while doing work. Ads go silent in the middle of streams and when ad is over, the stream continues as normal. Have not spotted a problem yet, probably watched around 40 or so random things to test it. Works exactly as advertised.

It works!

Seems to be working well

Works for now.

This add-on works well. I no longer have to worry about noisy ads.

Just installed it. Works like a charm automuting youtube ads. Very handy when I want to let the ads role to support the creator.

Work find on youtube.com, but when trying to use it on music.youtube.com it does not work. This behaviour seems to be intended though.

Works as advertised, no noticeable performance impact or unwanted side effects.

great addon! especially because recently youtube started cracking down on on adBLOCKERS, wonderful alternative to stop loud youtube ads from interrupting music sessions

Great addon works perfectly for me (FF on macOS). Consistently mutes all pre-video and interrupting ads, and unmutes afterwards. Practically no delays bar the occasional single word. YouTube is no longer a infuriatingly invasive corporate experience (long as you don't mind watching the hapless actors soundlessly selling their dignity for a few seconds). Many thanks to the developer 🙏

Also, I'm a coder though not a massive security expert, but have scanned the source code and found nothing that looks suspicious. This seems safe, but given the small user base I'm going to disable auto-updates and manually inspect any updated source code only if/when the addon breaks. You might want to do likewise.

Muting works always

The dev provided source code in commentsL +1.

An app that Youtube is not angry about.
One star deduction if the timer of the advertisement is at 0, then the advertisement must be skipped independently.

21 may 25 - now, not working many times
---------------------------------
25 jan 24 - mute more than 80% ....
---------------------------------
mute more than 97% youtube ads, but not 100%

Very nice solution for loud ads interrupting your video of interest.

Could you post a link to the source code?
