Amazing extension and supports different user-agents across containers. Great add-on and one of the reasons why I still use firefox for work (Need to sometimes fake an IE-11 user-agent in order to make websites work)

Great, you should really advertise ability to use a different UA per container more, didn't find another addon that does that yet.

I had several websites such as Google Ads that said the latest version of Firefox wasn't supported. This extension allowed me to appear as a chrome user on Windows and eliminated that issue. This extension does exactly what it says and has a ton of options. Thanks Devs!!

saya suka deng user agent tetapi user agent tidak bisa di pasang do frefox

Does not work anymore, most sites detect that a user-Agent switcher is being used and also some sites refuse to revert because mobile scaling is not in place. You need to update so that when you select a user agent it also scales the resolution of a mobile phone else the site will not go into mobile mode. Does not work until you get some new user-agents, implement automatic resolution scaling so that the page you visit is in a mobile phone resolution and add anti-detection methods. I think this add-on is dead since the developer is no longer responding which is a shame. Hope someone picks up a project like this and makes a better and updated add-on.

thanks you

While I like the extension it needs to be updated more often. Either that or post a user agent config file that users can use to update the user agents as needed. Right now it is a year behind. It recently got updated for Google Chrome so I hope to see it here soon. If so you will get a full 5 stars. Thanks.

Effective tool to fake user agents, BUT browser agents are always outdated by at least half a year!
It would be nice if they were automatically updated. The user interface could also use an improvement. One thing that would also be nice is an easy option to turn on a random user agent in a range of, say, the most common user agents.

It's a shame that this is the only user-agent extension recommended by Firefox
