Once installed, applications that don't use the network usually work out of the box.However, Tails has some differences in terms of additional configuration and network access.
Each application handles its configuration very differently, so we cannot give general instructions on which files have to be saved using the Dotfiles features.
Tails only allows connections to the Tor network. Additional software that uses the Internet must be configured to go through the Tor network otherwise, their connections are blocked by default for security.
