Open Firefox and navigate to any webpage (e.g., a search engine).
Tap the three-dot menu in the bottom-right corner.
Tap the ">" next to Extensions.
Select Be Focused and Productive and enter your parameters.

📌 Note: If you open the menu from a blank tab or the Firefox homepage, you may only see the Extensions management page instead of direct access to the extension’s functionality.

How to Block a Resource

Enter a part of the resource name in the left input field without specifying the protocol.
Example: Entering "youtube" will block all subdomains of this resource.
Enter the redirect URL in the right input field, fully specified with the protocol.
Example: "https://google.com"
Click the save button to apply the rule.

📌 Note:
- If the redirect URL is left empty, the target site will simply be blocked.
- To modify a rule, delete the old rule and add a new one.
