Well last night I did a windows update on my laptop (I used vista 32bit edition) and when I opened up firefox I noticed Microsoft left me a nice suprise.  A new firefox extension that I have no clue what it does (is this spyware?).

Since I couldn’t find out what it does I decided to remove it, but it seems that MS doesn’t want you to do that since it grays out the Uninstall button.  I think this extention only happens when firefox is the default brower (I rarely use IE now a days) and you use windows update to install a .NET Framework 3.5 SP1 update.  Anyway to remove it I found a nice page at www.dedoimedo.com/computers/ms-dotnet-firefox.html.
