As I read in https://wiki.mozilla.org/Windows_Service_Silent_Update, the helper process will run twice. Once for user level stuff and once for system level stuff. This is the success log of the first process.

The log shows that the maintenance service was unable to delete and existing updater.exe with the follopwing path
C:\Program Files (x86)\Mozilla Maintenance Service\update\updater.exe

Have you changed the permissions on either of the following?
C:\Program Files (x86)\
or
C:\Program Files (x86)\Mozilla Maintenance Service\

You can also try uninstalling the Mozilla Maintenance Service, verifying that the C:\Program Files (x86)\Mozilla Maintenance Service\ directory doesn't exist and if it does delete it, and then reinstalling Firefox.

Thanks for replying, Robert!
I checked again, uninstalled firefox and deleted the remaining
C:\Program Files (x86)\Mozilla Maintenance Service by hand.

Then installed a newer version, 55.0 and wait for it to update himself. And I don't know why - the autoupdate works now! Maybe a problem in an older version? 

Can you close this bug report please?
