navigator.userAgent always returns Firefox, no matter what I choose

It works, unlike others

I needed it for a particular website that only wanted to support Chrome. I downloaded this, installed it, and picked the only Chrome user-agent option (Chrome 59). The site then assumed I was on Chrome, but complained it was out-of-date so I couldn't use it. I found no way to use a newer user-agent, so this add-in does me no good.

Perfect

Периодически из-за этого расширения вылезает реклама.

I use it to manage my Instagram account from computer. It works perfectly!

Adding an option to disable uaswitcher for certain web sites would be great. Awesome add-on, with the latest browser versions, which is great since old browser versions can make some web sites complain. This doesn't happen with this add-on.

EDIT: I now see this, I hope it will be available at some point: "Are you refering to per-site User-Agent switching? That is currently the most asked for feature. It will be implemented once we know how to show it in the user interface."

Работает. Но если в настройках видно Linux Firefox десктоп то определяться может как Apple Safari т.е. неправильно. Хотя реально Андроид Firefox. Меняет, но не точно.

Do it's job

Very inconvenient way of importing the user agent in text form.

Hello! I decided to use your supplement. But the first thing I did not like was the lack of the ability to auto-update user agents. I thought I could solve this problem by manually adding agents through the site https://techblog.willshouse.com/2012/01/03/most-common-user-agents/ On this site there is a string display of agents for example:
"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36"
But when I began to add them, they were wrong. It turned out that these lines should be edited and indicate which client is available in fact - dekstop or mobile ... It's not convenient! Is the add-on not able to determine whether the agent belongs to the OS on the line "... (Windows NT 10.0, Win64, x64) ..."?

Doesn't save the agents wich have been added by the user.

Wonderful extension ! Comprehension and Well-designed.

good, but lacks list with domains where disabled

Best user agent spoofer because it has random mode and you can add your custom entries (e.g. that are most popular to reduce fingerprinting).
