Both YouTube and newer Add-ons for firefox say that I am running an outdated version, specifically version 2.0.0.9. However, when I check for updates in the browser firefox says that I am running the current version. I have uninstalled and reinstalled version 3.6.6 from the Mozilla website multiple times to the same result.

This happened

Every time Firefox opened

Your User agent is wrong

1. In the Firefox Location Bar, Where you enter the address of web pages, enter about:config

2. A "This might void your warranty" warning may appear. Click "I'll be careful, I promise!"

3. In the Filter text box, enter general.usergent

4. For each of those general.useragent preferences, right click them and choose reset.

You should be okay now.
