Read-only.

However, yes I agree that private browsing should default to read-only, 
as any time you interact, you expose something of yourself, whether by 
what you're responding to, how you write, or what view or opinion you 
are expressing. Tor users need to be aware that any interaction while in 
privacy mode is a liability, and it is proper that they have to actively 
enable some option to enable interaction.
