About this extension

Looks like a speaker, Barks like Ultra-Sonic Cross Device Tracking Dog Whistle. ^_^ Thanks to the Advertising Companies like Silver-Push, the Power of JavaScript Embedded in Websites and Microphone Permissions in Smart Phones. Your devices can be linked and associated with the near by Devices around you. Use SilverWall FireFox Add-On as part of your tool-chain to prevent this kind of sneakiness.

Developer comments

Was originally a Chrome EXT Add-On from GitHub. I converted it to a FireFox EXT and Uploaded it to the FireFox Add-ons repos for convince and to increase discoverability of these anti-XDT technologies.
