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.

This is first time with an Android phone

Funcionou perfeitamente.

Not user friendly, Terrible UI. User Can't simply SAVE custom user-agent strings. for standard use, FAQ (its really a "FA-Q") must be read.

Doesn't seem to be designed for easy mobile use

Great addon
