like it, except for... Rated 4 out of 5 stars

...the annoying green counter - very bad idea and it looks like it is not possible to remove

Disconnect seems to be a fiddle-free extension for the most part, so why does it need a counter at all?

please change the icon color instead and dump the counter :)

and for the web-knowledgeable, you can dump the built-in whitelist and replace it with:
{"":{"Google":false,"Twitter":false,"Yahoo":false,"Facebook":false,"LinkedIn":false}}
note that this may/will break some sites!
the pref is:
extensions.disconnect.whitelist

This review is for a previous version of the add-on (3.9.1). 

You beat me to replying :-)

(Since you can only reply 1x on AMO, I try to wait till we fix a reported bug or add a requested feature so the reviewer knows the change is live. Thanks for the updated review.)
