I absolutely hated Firefox 29 and expressed my feelings both in support and in feedback. The user interface changed completely and horribly, for no apparent reason and with total disregard for user convenience. Happily I was able to return immediately to Firefox 28 and all my customizing by restoring to an earlier point and disabling automatic update. However, I am concerned about losing the security features of newer releases, though I don't know how important they really are. Now I see that Firefox 30 has emerged. Does anyone know whether Firefox 30 reverts to features of earlier versions that so many of us prefer or whether it goes further down the hated Firefox 29 route?
