It now works, Thank You. (1) renamed the directory. (2) yum upgrade firefox = 31.5.3 (3) started Firefox and got a horrible nightmare - ugly tabs, no menu bar and all my familiar settings gone. It was a real devastating and emotional shock. It prompted me to do a backup ! (4) closed Firefox (5) renamed the new directory *-crap (6) restored the previous directory (7) restarted Firefox and everything was familiar and wonderful again. Thanks for your very effective solution. Paul. England, EU.
