  • Firefox 59.1 64-bit and this addon does NOT work
  • 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 The site then assumed I was on Chrome, but complained it was out-of-date so I couldn't use it.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).
