This addon is easy to use, works well, and is kept (mostly) up to date with browser releases. I appreciate the option to add custom UA strings, and to modify the default ones.

I was looking for a WebExt-compatible alternative to user agent overrider. This one is perfect! Thanks for your work

That every time I have a problem with the following link this always helps

Thanks! Tiny, self-explaining, yet powerful and comfortable.

this is a very good user agent switcher for Firefox 57* It works great. I would say, it is the best, because i can add cusom user agents. Thank you
