Well done Rated 5 out of 5 stars

Simple, straight-forward, customizable, easy to switch. Currently using as necessary part of watching Netflix on Firefox 49. Note that certain settings force mobile version of Google Drive. Just set UA to "Default" and F5 to refresh.

Tested everything... Rated 5 out of 5 stars

And this is the best user agent addon. Thank you for this great tool, man!

Thank you Rated 5 out of 5 stars

Works great and, unlike others I've tried, this addon remembers your chosen (or custom) setting when you restart the browser.

Very useful Rated 4 out of 5 stars

Very useful. Website developers think all users are just average users and try to decide for you what you need to see on their sites, just by reading the user agent.

This is the anti-dote.

Thanks to the developer for a making this available.

Any way to reset to default (other than disabling the extension)? A 'default' option in the list of choices would be helpful. Editing the preferences in the extension does not seem to work.

Thanks again!

It works with Waterfox (v 39) Rated 4 out of 5 stars

This extension works with Waterfox as well as Firefox. Waterfox is essentially the previous version of Firefox, but compiled for 64 bit computers.

@ C-Wizard, re: Netflix/Firefox 29...
I had the same issue, but it has a very easy fix!

Bring up the list of options and click "preferences" - under the "# Windows" section, add the following line:

Windows / Firefox 38: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20100101 Firefox/38.0

Click the close button, pull up the drop-down menu again and select the new "Windows / Firefox 38" option.

Voila! Netflix will once again believe the wonderful lies this add-on tells it.

As for my opinion of this add-on itself, I absolutely love it! Very simple and easy to use, does exactly what it's supposed to and issues like this latest Netflix one can be easily remedied without having to wait for an official update.

Smart User Agent Overrider Rated 5 out of 5 stars

It is smart because you can personalize and select your UA like and it still selected when you exit/back the browser...

Funciona, pero es muy limitado Rated 2 out of 5 stars

El cambio de agente de usuario es global usando este complemento: no permite configuraciones personalizadas por dominio, sino que usa el mismo para todas las webs que visitéis; tampoco permite cambiar el agente de usuario de JavaScript.
Hace su función pero si alguien necesita una herramienta mas fina, que use algo como Ua-site-switch o UAControl combinado con User-Agent JS Fixer
