Plugins are installed in German
I am an American using Firefox in English but living in Germany. I have my browser language set to English, but whenever I install a Plugin it installs in German and I need it in English.

Are you aware that you have the German localization of Firefox installed?
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; de-DE; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13
I reinstalled an English version of Firefox and reinstalled the plugins but they're still in German.
Do you mean plugins on the Tools > Add-ons > Plugins or do you mean extensions (Tools > Add-ons > Extensions)?
Your More system details list list shows English plugins.
