I just tried to upgrade Firefox and got this message when I tried to put the icon in the applications folder: The operation can’t be completed because the item “libsmime3.dylib” is in use. How do I deal with this? Thank you.
I have been using an old version of Firefox without difficulty. I need to install as I am using Zotero to do research and it only runs on Firefox.
