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.

I use this as a user-agent switcher (manually select a single chrome version, turn off and on as needed) since all the other user-agent switchers I tried didn't work for me. Chameleon works flawlessly! :)

Extremely comprehensive privacy add-on.
I really recommend this module to spoof your browser.

jaj

Hey man I absolutely appreciate what you're doing, great add-on!

But could you please remove IE11 from the standard spoofing options? I mean, deactivating it is easy but nobody uses it anymore and almost every site I visit with this particular spoof doesn't work and tells me to update my browser. You could still keep the user agent but make it optional, not included in the default settings.
