Go with 4. Update to Sierra, it will save you most trouble in the long 
run. No need at all to go to a store to get it done though, just do it 
yourself.... Download the updater from the App Store and follow the 
instructions. Firefox and LibreOffice might also need updating, if you 
haven't kept them up to date, but both will work fine in the newer OS.
