Doesn't increase the volume - instead when you turn the slider, it mutes the volume until you F5 the page.

As a deaf person with 7% left, this add-on has been such a lifesaver when I only need a tab to be louder and not my entire PC!

i love you. amazing very helpful.

按2~6以后，会把进度条改成200~600%，但是音量调节并没有生效。需要再按左或者右才能生效！！！！！！！！！！！

Good addon

I need to watch a video for my Calculus class and it's incredibly quiet. Even with my volume at 100% and everything else maxed out, it's still pretty quiet. This extension actually made it louder, doing exactly what it says it does. I'm really happy about this.

loving it especially the fact that I can prolong my hearring loss
