"libsmime3.dylib" in use blocks deleting Firefox from Trash

Tried to install the new download of Firefox 3.6.16

When I did, it said it couldn't install because the libsmime3.dylib was in use.

I trashed the Firefox application and profiles folder by dragging box into the Trash.

But when I go to empty trash, the Firefox application will not delete and the same message comes up "libsmime3.dylib" is in use. And then when I click "continue," three of four more "lib" files come up as in use. That leaves Firefox application still in Trash, and I can't install a new version.

Help, please...
