Update Portable Firefox - Simple & Easy Guide

Updating Portable Firefox: A Simplified Guide
Do you appreciate the convenience of using a portable Firefox browser, but encounter difficulties when attempting to update it to the latest release? Updating your portable browser can now be as straightforward as updating a traditionally installed version of Firefox. Please note that this procedure is specifically designed for portable versions obtained from John T. Haller/portableapps.com.
Getting Started
Initially, you must download the standard .exe installation file directly from the Mozilla website. Once downloaded, you're prepared to begin the update process.
Installation Process Begin by double-clicking the .exe file to initiate the installation sequence and then select “Next”. Upon the appearance of the subsequent window, choose “Custom” and uncheck the option to “Use Firefox as my default browser”. Proceed by clicking “Next”.

Selecting the Installation Directory
The next screen displays the default installation location for Firefox. At this point, click “Browse” to navigate to the directory where your portable browser is stored.

After locating your portable browser’s home directory, you’ll need to delve further into its structure to identify the appropriate installation destination. (In this example, the home directory is named “Portable Firefox” and resides within the “Program Files” folder.) Select the “Firefox” folder, which is located inside the “App” folder, and click “OK”.

It’s important to note that your profile folder, containing your personalized settings, is situated within the “Data” folder, separate from the installation location. This ensures that your preferences, extensions, themes, and other customizations remain intact during the update.
The complete installation path will be “C:\Program Files\Portable Firefox\App\Firefox\”. Click “Next”.

Finalizing the Installation
The subsequent window presents options for creating shortcuts. Deselect all three shortcut options and click “Next”.

The final window should only display the designated installation location for your portable browser. You are now ready to proceed with the installation and update your portable Firefox to the newest version.

After the update installation is complete, be sure to deselect the “Launch Firefox now” option. Click (or double-click) your preferred portable Firefox shortcut to launch the updated browser.

Conclusion
This method also provides the flexibility to switch your portable Firefox to a different language version. Furthermore, it allows you to experiment with the latest beta and alpha releases of Firefox without impacting your standard Firefox installation.
