Hi, the issue with 'earr*pe' is from the youtuber they often don't normalize volume and if they do they create ultra loud 'earr*pe' as a 'meme' especially people like pewdiepie they always did a really loud sound for comedic affect.
The only resolution to do that is normalize the volume on your site, as noise normalization requires such logic that it ties into your system drivers.
As for reddit it should be working if you granted the permissions as stated in the latest patch notes lmk.

The latest revision, where you lowered your rating in fact made it work on this site.


I've reverted the extension to the previous release on FireFox.com
Hi, I was contemplating for awhile weather I should add more functionality, but it would require more permissions. This new update checks iframes for content. Previously only checked tabs, so it worked on less sites.
I might make two branches, I’ll revert this and make this branch “reduced permissions” and release a new extension (extra functionality).

Thanks for liking my extension. I hope you also enjoy the most recent set of patches. Please let me know if you prefer the circle or the stick? I don't know in what circumstance you would need more volume, if I play most things more than 10dB above the default, it will start clipping.

Hope you like my recent changes, you can now manually type in a different value, it took me many hours to implement something that seems so easy.
