This is not an out-of-the-box solution. First you have to manually add the toolbar icon. Then, for complete functionality, you will need to download and import the XML file from http://techpatterns.com/forums/about304.html (the default user-agent settings are pretty worthless).

Every time you restart Firefox the User-Agent is reset which is a shame. I needed this to view mobile-only games on my desktop. For that it works just great. 4/5 for functionality and would have been 5/5 if not for the above.

It is worth reading the following link before writing a report or filing a bug: http://chrispederick.com/work/user-agent-switcher/help/#user-agents
