/*
 * Description of Tests:
 *
 * Test load page and reload:
 * 1. Enable HTTPS-First and the pref to trigger beforeunload by user interaction
 * 2. Open an HTTP site. HTTPS-First will try to upgrade it to https - but since it has no cert that try will fail
 * 3. Then simulated user interaction and reload the page with a reload flag.
 * 4. That should lead to a beforeUnload prompt that asks for users permission to perform reload. HTTPS-First should not try to upgrade the reload again
 *
 * Test Navigation:
 * 1. Enable HTTPS-First and the pref to trigger beforeunload by user interaction
 * 2. Open an http site. HTTPS-First will try to upgrade it to https - but since it has no cert for https that try will fail
 * 3. Then simulated user interaction and navigate to another http page. Again HTTPS-First will try to upgrade to HTTPS
 * 4. This attempted navigation leads to a prompt which askes for permission to leave page - accept it
 * 5. Since the site is not using a valid HTTPS cert HTTPS-First will downgrade the request back to HTTP
 * 6. User should NOT get asked again for permission to unload
 *
 * Test Session History Navigation:
 * 1. Enable HTTPS-First and the pref to trigger beforeunload by user interaction
 * 2. Open an http site. HTTPS-First will try to upgrade it to https - but since it has no cert for https that try will fail
 * 3. Then navigate to another http page and simulated a user interaction.
 * 4. Trigger a session history navigation by clicking the "back button".
 * 5. This attempted navigation leads to a prompt which askes for permission to leave page - accept it
