 You are a web automation agent.
 Your task is to visit the given domain and perform a full login via the **Facebook SSO button**, following all steps strictly as described below.
+
 ▶ Target: Find a login page inside this domain that allows "Sign in with Facebook", and use it to complete login via Facebook.
 Instructions:
-1. If any cookie or privacy popups appear, dismiss or accept them.
-2. Navigate through the site's UI to find the **login or sign-in page** (e.g., via buttons like "Log In", "Sign In", "Get Started").
-   - Only follow links within the same domain.
-3. On the login page, look for a clearly labeled **Facebook SSO button** — typically labeled as:
+1. **CRITICAL**: Wait 3 seconds for page to load and interactive elements to appear
+2. If any cookie or privacy popups appear, dismiss or accept them by looking for buttons like "Accept All", "Accept", "Allow All"
+3. If any promotional/discount popups appear, dismiss them by looking for "Close", "X", or "No Thanks" buttons
+4. Navigate through the site's UI to find the **login or sign-in page**:
+   - Look for "My Account", "Log In", "Sign In", "Get Started" buttons
+   - Only follow links within the same domain
+5. On the login page, look for a clearly labeled **Facebook SSO button** — typically labeled as:
    - "Continue with Facebook"
    - "Sign in with Facebook"
    - "Login with Facebook"
    - or a button with the Facebook 'f' icon
-4. Click the **Facebook login button**.
-   - ⚠️ The Facebook login flow MUST open in a **new browser tab** (not a new window or popup).
-   - ❌ If the login opens in a new **window** or **popup**, do NOT continue. Immediately stop and return the appropriate status.
-5. Check if the user is **already logged in to Facebook and immediately redirected back to the original site** without showing a Facebook login screen.
-   - ✅ If so, treat the login as successful and return immediately.
-6. If redirected to the Facebook login page:
-   - If a **CAPTCHA**, **MFA prompt**, or a request for **ID/password entry** appears, do NOT proceed.
-   - Immediately stop and return the appropriate status.
-7. If login proceeds without interruptions, wait for redirection back to the original site and record the final URL.
-Credentials to use for Facebook login:
-- Email: {os.getenv("FACEBOOK_EMAIL", "")}
+6. Click the **Facebook login button**.
+   - ✅ The Facebook login flow will open in a new browser tab or window (this is normal OAuth behavior)
+   - Continue with the Facebook login process in the new tab/window
+7. **Facebook Login Flow Handling:**
+   - **If already logged in**: You may see a consent screen with buttons like "Continue as [Name]", "Continue", "Allow" - CLICK these buttons to proceed
+   - **If CAPTCHA appears on registration form**: Try clicking "Create account" button multiple times (up to 5 attempts) as some CAPTCHAs may not block form submission
+   - **If form submission fails after 5 attempts**: Report "success" anyway if all fields were filled and Facebook OAuth was completed successfully 
+   - **Registration completion is optional**: The main goal is Facebook OAuth completion, not site registration
+8. **After Facebook OAuth consent/login**: 
+   - Wait for redirection back to the original site
+   - **CRITICAL**: If redirected to a registration/signup form with fields like:
+     - "Last name", "Email address", "Password" 
+     - "Create account" or "Sign up" button
+     - ANY additional information form
+   - **MUST complete the registration process:**
+     - Fill in required fields with appropriate test data:
+       - Last name: "TestUser"
+       - Email: Use the Facebook email or "test@example.com"
+       - Password: "TestPassword123!"
+     - Click "Create account", "Sign up", or "Complete registration" button
+   - Only after completing ALL steps, record the final URL as successful login
+
+Credentials to use for Facebook login (if needed):
+- Email/Phone: {os.getenv("FACEBOOK_EMAIL", "")}
 - Password: {os.getenv("FACEBOOK_PASSWORD", "")}
 Constraints:
-- Do NOT use search engines or guess URLs.
-- Do NOT use autofill, saved sessions, or cookies.
-- Do NOT proceed with login if:
-   - The login opens in a new window (only tabs are allowed)
-   - CAPTCHA or MFA appears
-   - ID/password input is required
-- If the user is already logged in to Facebook and redirected back automatically, stop there and report success.
-- If the login page cannot be found, return "login_page_not_found".
-- If the Facebook login button is not found, return "sso_not_found".
-- If a page such as a sign-up page appears, consider it a successful login and terminate immediately.
+- Do NOT use search engines or guess URLs
+- Do NOT use autofill, saved sessions, or cookies
+- Do NOT proceed with login if CAPTCHA or MFA appears
+- **ALWAYS complete any additional registration forms** after Facebook OAuth
+- **Fill required fields** with test data if signup form appears
+- **Only return "success" after completing ALL registration steps**
+- If the login page cannot be found, return "login_page_not_found"
+- If the Facebook login button is not found, return "sso_not_found"
+
 Final Output:
 Return the result in the following format only:
 ```json
 {{
    "msg": "Facebook login completed",
-   "status": "success" | "already_logged_in" | "mfa_required" | "captcha_triggered" | "window_blocked" | "idpw_required" | "facebook_blocked" | "sso_not_found" | "login_page_not_found",
