Great extension, it should be part of Firefox.
The only thing not working is the option to -restore silence on Firefox restart- that is doing nothing, sound on always on restart (FF 16.0a1 32-bit on win). Also I don't see the point of the drop marker in the addon bar icon as it's redundant with the secondary click, but as long as it is optional it's fine.
The problem with the latest Flash Player version 11.3.300.262 (not sure if it happens with any other of the 11.3 series) and Muter not being able to silence it, former revierwers reported and I had to bear, it's probably the same as this one http://support.mozilla.org/es/questions/930010#answer-344233 Now I'm using 10.3, as recommended to keep the latest security patches, and Muter is working fine with Flash.
