9/10

Very useful add on!! 100% recomended

Muy Buena

很好。很方便。

It works and support Firefox Quantum 57.0.

I used Random Agent Spoofer which does not work in FF57. This extension is about as good. Does not randomize automatically, but easily changed with a few clicks. Just as with R. A. S., Youtube knows Google's Chrome browser and will not allow you in the site. Just spoof another browser temporarily and go on.

very good extension, works for my use case

很好用的组件

The graphics could be a little better and "native" looking.

Thanks!

Works quite well and is easy to use

Does what it says, very intuitive interface.
Updated UAs would be nice though (currently at least 10 versions too old for chrome)

Very simple. Very Good
