It seems that your user has all needed permissions to view the in-line editing gear. I've tested setting in-line permissions to a user that doesn't have any additional ones set and he was able to see the editing tool in the fron-end. Thus you don't need to be in the role of administrator to be able to you the browse and edit functionality. Try restarting your application (resaving the web.config) and cleaning the cache of your browser and see if that fixes the problem.
