For some reason Finder always restores all my previously open tabs even after I've restarted the system. This is unnecessary for me and in just several days my Finder is really clustered up and I had to close the tabs one by one. There must be a setting to disable such behavior?
You have the option at Shutdown or Restart for whether or not to reopen windows...
though it does include whether to reopen Apps, too
If you want only the Finder to not save its state, try this in Terminal
defaults write com.apple.finder ApplePersistenceIgnoreState YES
You can revert the setting using
NO instead of
