This is a good user agent switcher! It will change the user agent to your selection and it also provides a direct link to download additional user agents. I've ran this against FF24, FF25 and FF25.0.1

For 24, the appName and User agent will be changed to your selected user agent type. For example selecting MSIE, the navigator appName will reflect "Microsoft Internet Explorer"

In 25 and 25.0.1, the user agent switches perfectly but the appName will remain as Netscape, no matter which user agent you select. I think 25 and 25.0.1 may have broken something that this plugin uses.

I will be submitting a bug report. Still a A+++ plugin!
