- * Description of the Tests for

- *
- * 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.

- * Double redirect cached image tests
- * 8. Using offline mode to ensure we hit the cache, load a cached image over
