How to activate Opera private-browsing mode by default

Opera has a command-line option to enable private-browsing mode.

Add -newprivatetab to the command-line option (that’s a space, one dash, and then newprivatetab). Click OK.

Opera will now open a private-browsing tab whenever you launch the shortcut. Note that Opera has per-tab private-browsing settings, so this tweak will only open a private-browsing tab when you launch Opera. You will have to open new “private tabs” instead of normal tabs while using Opera to continue using private-browsing mode.
