While checking on another situation, I went to system preferences, then users and groups, and then to login items. I find two items are duplicated (Firefox and Flux). Should they show up duplicated? Should I delete one of each, and how do I choose which to delete so I continue to get the items desired to load when signing on? I don't appear to be having any real problems (read that too many items could slow down my computer), but if improvement could be served with updating these items, I am all for making the "fix".
