How do I set/unset Tasktop as the default browser?
Navigate to Window > Preferences > Tasktop > Windows and place a check in the “Set Tasktop as default browser…” check box to enable. Clear this check box to disable using Tasktop as your default browser. Note that enabling this option will cause Tasktop to act as your default browser only when running. When Tasktop is not running, your former default browser will become the default.
