Firefox is unable to update to 7.0.1. I get an error that The operation can’t be completed because the item “libsmime3.dylib” is in use. I found this is a Cisco folder, tried to trash it, but it won't leave. Maybe I need it?

The operation can’t be completed because the item “libsmime3.dylib” is in use.

This is the error message I get when i try to install the 7.0.1 update. I found a cisco folder on my MAC and tried to Trash it. It won't leave. Maybe I need it... Some of it did Trash, but what ever is left continues to prevent 7.0.1 from installing.

OK I looked at an old Apple forum and someone suggested Trash then Restart then Empty Trash, and it worked. Cisco is gone, Opt is gone, and I was able to load FireFox. I had to give admin passwords to do this too. Why an old weird game or library folder could cause such obstacles is a wonder. But I'd rather wonder about other things...
