This is an English support forum. For support on your language, refer to its own community. Anyway, as Google Translate tried to tell me: Firefox 15.0 beta LONG installs updates, and other versions of Firefox faster I think you mean you want to stop automatic updates. Check here, please, and you will see how to disable updates or whatever you tried to tell me. If that's not your issue, translate it better than Google to English.
