slow to load. resets your settings without input requiring you check them before starting. Old user agent lists need updating.
good for faking out anti-free speech bad website moderators-there are so many. need a good guide on how to best make your fingerprint useless to trackers and censor sites. It seems to work on some sites and not on others. True time zone was detected even when "spoofed". it's spoof settings work on "cover your tracks" but I'm guessing some sites they do not work. It's a cat and mouse game. Fingerprinting is evil and we really need a good undetectable spoofer.

This extension make me more secure on web.

This extension WILL randomly delete your settings and it WILL fail in importing your previous settings:

"Invalid setting value: options.webRTCPolicy"

Doesn't matter what version the settings backup was from, the extension is useless.

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. :(

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.
