/*
 * Test that the Tracking Protection section is visible in the Control Center
 * and has the correct state for the cases when:
 *
 * In a normal window as well as a private window,
 *   With TP enabled
 *     1) A page with no tracking elements is loaded.
 *     2) A page with tracking elements is loaded and they are blocked.
 *     3) A page with tracking elements is loaded and they are not blocked.
 *   With TP disabled
 *     1) A page with no tracking elements is loaded.
 *     2) A page with tracking elements is loaded.
