Thank you for this invaluable extension.

This extension make me more secure on web.

This plugin is very helpfull and works efficient.

Youtube stopped working with this add on, also couldn't login to Twitch. Disabled for now..

Waouh the best extension ever made ! I try many many UA extensions... I use it to change UA only for some web sites in the white list. Run very well on Android Firefox. Many thanks sereneblue !

works perfectly, tested on covermytracks

It's pretty great, does what it says it does, tested it with am i unique, and it helped quite a bit. Only issue is that when you change your screen size through the extension, some websites may or may not break. but that's just normal, i suppose.
