Highly recommended! This plugin is amazing; it randomly generates your device.

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

In a world where everything is spying on everyone; having chameleon to spoof your browser is invaluable!

Right now, the biggest problem with this add-on is that it tends to not always work well on some websites, so I haven't used it as much as I would've liked. For example, it causes problems on YouTube, and sites protected by Cloudflare always put me into this annoying endless captcha loop if I'm using a custom profile.

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 !

UI is nice, but it doesn't really seem to spoof very well... Most sites still immediately know I'm using Firefox when I have this set up to spoof Chrome. Only sites that check solely the User Agent string think I'm on Chrome; any other "detection method" returns Firefox for me. :(

好

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.

very good and stable

Only two stars because websites can still detect your true OS which can defeat the purpose if you are spoofing to a Linux browser. Otherwise, it's GUI is nice.

Works excellently on Android. Many more settings than other user agent spoofer add-ons.
