Mozilla unblocks Microsoft .net

UPDATE: Mozilla has now removed the extension from the blocklist after Microsoft clarified some information in its bulletin on how Firefox users were affected. I'll attempt to get to the bottom of what appears to be a case of miscommunication ]

Mozilla has added the Microsoft .NET Framework Assistant add-on to its blacklist, a move that effectively disables the dangerous extension and plug-in for all Firefox users.

The move comes in the wake of an admission from Microsoft that the add-on was exposing users to drive-by malware downloads via a remote code execution vulnerability.
