Very nice..

Helps me to get the upgraded experiences that devs allow only on a specific device, thanks!

Looks perfect after installation (A LOT OF BROWSERS and versions to choose)! Lets see how it will works in future.

UI is clumsy but fairly usable. Otherwise, works fine.

amazing extension, thank you

What I and others would really like is a much smaller button. It takes up way too much room on the URL Bar in Firefox .. Or at least, give us an easy way to minimize the UI Button after we select a User Agent to use. Otherwise, this is a pretty add on. I like that the developer continues to update the agent strings. Youtube has changed the way they do things and you need to allow Ads in order to see Notifications or make a Comment on a Video om Youtube .... Luckily, not a big deal, as the ads are short and you can skip them.

Useless. Does not work on https://music.apple.com/ running FF75 on windows 10.
