Today I noticed an add-on I didn't install to my firefox browser, .net framework assistant. Seems microsoft wanted to add some security weaknesses into firefox allowing instillation of programs without the user's knowledge.
To ensure we have the weakened security they make it difficult to remove said unwanted addon (if you've got it, you'll notice the uninstall button for this addon won't work).
I followed the instructions here to remove it. http://www.annoyances.org/exec/show/article08-600
Well, I need to go take Mom to a Dr.'s apt. now.
