For security reasons, Magento says to change the file and folder permissions after install.
Can this be done from the backend via:
System -> Magento Connect -> Magento Connect Manager -> Settings -> Use Custom Permissions?
If so, what are the safest settings in that panel for Folders and Files?
you should use SSH to set the file & folder permissions using command line.

Thank you for the suggestion.
I am aware of information in the manual. However, this is rather complicated to set up and it makes it impossible to install extensions via the Magento Connect Manager in the backend. So I hoped to be able to easily change the permissions via the backend.
What exactly are those settings for in: System -> Magento Connect -> Magento Connect Manager -> Settings -> Use Custom Permissions?
Thanx in advance to share your thoughts with me once more.
