Please describe your issues better. You are running a Beta Firefox.

Note that you use a Beta version. The Firefox 38 beta versions receive an update twice a week. If you do not like that then you can uninstall the beta version and install the current release.

You can find the full version of the current current Firefox release (37.0.2) in all languages and all operating systems here:

Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
