If you take a look at the installed add-ons in Firefox you might notice an add-on called Microsoft .net Framework Assistant. That add-on is different from most other installed add-ons. The first thing that you will notice is that you cannot uninstall it as the uninstall option is inactive in Firefox. You might also realize that you did not install that add-on actively which means it must have been installed by another application.

The Firefox Extension Guru posted a walkthrough on how to remove the Microsoft .Net Framework Assistant. It basically comes down to the following steps (it might be a good idea to backup all data before proceeding).

Make sure Firefox is closed.
Go to C:\WINDOWS\Microsoft.NET\Framework\v3.5\Windows Presentation Foundation\DotNetAssistantExtension in Windows Explorer and delete everything in that folder but keep the folder name.
Start Firefox. The add-on should not be in the list anymore.
Type about:config in the Firefox address bar.
Filter for the entry general.useragent.extra.microsoftdotnet
Right-click that entry and select Reset

The process is apparently a bit more complicated for Firefox 3.1 beta versions as the Microsoft .Net Framework Assistant is not yet compatible with that version of Firefox and thus not completely installed.
