/*
 * Description of the Tests for
 *  - Bug 418354 - Call Mixed content blocking on redirects
 *
 * Single redirect script tests
 * 1. Load a script over https inside an https page
 *    - the server responds with a 302 redirect to a >> HTTP << script
 *    - the doorhanger should appear!
 *
 * 2. Load a script over https inside an http page
 *    - the server responds with a 302 redirect to a >> HTTP << script
 *    - the doorhanger should not appear!
 *
 * Single redirect image tests
 * 3. Load an image over https inside an https page
 *    - the server responds with a 302 redirect to a >> HTTP << image
 *    - the image should not load
 *
 * 4. Load an image over https inside an http page
 *    - the server responds with a 302 redirect to a >> HTTP << image
 *    - the image should load and get cached
 *
 * Single redirect cached image tests
 * 5. Using offline mode to ensure we hit the cache, load a cached image over
 *    https inside an http page
 *    - the server would have responded with a 302 redirect to a >> HTTP <<
 *      image, but instead we try to use the cached image.
 *    - the image should load
 *
 * 6. Using offline mode to ensure we hit the cache, load a cached image over
 *    https inside an https page
 *    - the server would have responded with a 302 redirect to a >> HTTP <<
 *      image, but instead we try to use the cached image.
 *    - the image should not load
 *
 * Double redirect image test
 * 7. Load an image over https inside an http page
 *    - the server responds with a 302 redirect to a >> HTTP << server
 *    - the HTTP server responds with a 302 redirect to a >> HTTPS << image
 *    - the image should load and get cached
 *
 * Double redirect cached image tests
 * 8. Using offline mode to ensure we hit the cache, load a cached image over
 *    https inside an http page
 *    - the image would have gone through two redirects: HTTPS->HTTP->HTTPS,
 *      but instead we try to use the cached image.
 *    - the image should load
 *
 * 9. Using offline mode to ensure we hit the cache, load a cached image over
