This pesky little piece of shit came along with the .NET 3.5 Framework update.
Surely they could of at least ASKED me if I wanted to install it, then I wouldn't of minded so much.
But no, a backhanded tactic was applied and thus I will treat it as I would with the likes of trojans and spyware.
To remove it, navigate to:
- for 32bit operating systems:
"HKLM\SOFTWARE\Mozilla\Firefox\Extensions" - for 64bit operating systems:
"HKLM\SOFTWARE\Wow6432Node\Mozilla\Firefox\Extensions"
Once found, remove the key pointing to the .NET Framework directory.
