3. Navigate to the Firefox Directory: Open a terminal and navigate to the extracted Firefox directory.
4. Install Firefox: Run the following command to install Firefox:
“`bash
sudo ./firefox-installer
“`
5. Remove the Old Firefox Version (Optional): If you want to completely remove the old version, use the following command:

“`
6. Restart Firefox: Launch Firefox to enjoy the updated version.

Troubleshooting Common Update Issues

While updating Firefox is generally seamless, you might encounter occasional issues. Here are some solutions:

• Missing Dependencies: If the update fails due to missing dependencies, run the following command to install them:

“`bash
sudo apt install -f
“`

• Network Connectivity: Ensure you have a stable internet connection during the update process.
• Insufficient Permissions: Use `sudo` before all commands requiring administrator privileges.
• Outdated Package Manager: If your package manager is outdated, update it using:
