Aim: The goal is to disable Private Browsing mode in Firefox, ensuring that it cannot be used on the system.

I have spent hours on this. With no luck.

      1. Steps Attempted:

  - Select "Options" or "Settings".
  - Go to "Privacy & Security".
  - Scroll down to the "History" section.
  - Change the setting to "Use custom settings for history".
  - Uncheck the box next to "Always use private browsing mode".
  - Restart Firefox.

3. **Using about:config**:

  - Open Firefox.
  - Type `about:config` in the address bar and press `Enter`.
  - Accept the Risk and Continue.
  - Search for `browser.privatebrowsing.autostart`.
  - Double-click on it to change the value to `false`.
  - Restart Firefox.

4. **Creating a New Firefox Profile**:

  - Open Firefox.
  - Type `about:profiles` in the address bar and press `Enter`.
  - Click on "Create a New Profile" and follow the prompts.
  - Launch the new profile in a new browser.
  - Go to "Privacy & Security" settings and ensure "Always use private browsing mode" is unchecked.
  - Restart Firefox.

5. **Refreshing Firefox**:

  - Open Firefox.
  - Click on the hamburger menu (three horizontal lines) in the top-right corner.
  - Select "Help" and then "More Troubleshooting Information".
  - Click on "Refresh Firefox" and confirm.

6. **Checking Firefox Policies**:

7. **Uninstalling and Reinstalling Firefox**:

8. **Registry Edit (Windows)**:

  - Navigate to the following key:
    ```

      - Right-click on the **`Policies`** key.
      - Select **`New > Key`**.
      - Name the new key **`Mozilla`**.
      - Right-click on the **`Mozilla`** key.
