webextension + multiprocess = good. Works as expected. Thank you.

Works perfectly. It's pretty easy to add custom UA. So easy to use, simple UI and pretty powerful. All stars I'll give to you for your hard work. The new random user agent feature just make this addon even more powerful. And dev is pretty helpful, if you ever encounter any issues or maybe just want to send feedbacks, just post it on the gitlab (http://bit.ly/2wpyVdR) and he will help you as soon as he can. Keep up the great work, dude!

Brillian fork, brilliant. Keep up the great work, mister.

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

Good add ons

Bin neugierig was dieses Add on macht und kann.

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
