Marcia: since frames 1..7 are mcffplg.dll, it's safe to say this is McAffee and not a random extension. We've recently given them a home of their own...

And if the change i'm making to the signature doesn't work, please fix socorro so that it does.

Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at

If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
