Please provide more information Rated 3 out of 5 stars
No icon, no options, works in the background, OK. But what does it perform precisely ? Moreover, the add-on home page is absent (http://disconnect.me/google). Please do provide at least a basic description of operations. 3 stars because I'm granting blindly.This review is for a previous version of the add-on (126.96.36.199-signed).
More on the way
We plan to add a button to the URL bar to indicate blocking activity and enable unblocking.
And the homepage link is live now (the add-on got approved too fast for us!).
But I think the description says it all — if you want, you can see the (many) blocked third-party services by reading the source at https://github.com/disconnectme/gdc/blob/master/firefox/chrome/content/overlay.js (look for the domains).
