Portable Firefox OSX is designed to run independently of the operating system’s installed programs, allowing users to carry their web browser setup on a portable drive (USB, external SSD, etc.). Although macOS doesn’t have an official portable version, creating a portable Firefox involves setting up the browser and its user profile on an external drive so that all your settings, extensions, and history travel with you.

Key Features of Portable Firefox for macOS:

Portable User Profile: Firefox Portable uses a self-contained user profile stored on the external drive. This includes your bookmarks, browsing history, passwords, extensions, and preferences. You can run the same customized Firefox on any macOS machine without leaving traces on the host system.
No Installation Required: Portable Firefox doesn’t require installation. You simply run the Firefox app directly from the external drive, making it ideal for situations where installation privileges are restricted.
Customizable and Sync Capabilities: All standard Firefox features are available, including themes, add-ons, and settings. You can sync your portable Firefox with your Mozilla account to maintain bookmarks, passwords, and history across devices while keeping your portable setup.
Privacy and Security: Running Firefox from an external drive ensures that no browsing history or settings are saved on the local machine. This can be useful for enhanced privacy, especially on public or shared computers.
Multiple Instances: Firefox Portable can be run concurrently with other Firefox instances installed on the machine without interfering with the local profiles.
Cross-Platform Functionality: While this is primarily for macOS, you can also create a similar setup for Windows or Linux systems. You can carry the same Firefox instance and profile across platforms if needed.
Portable Updates: Firefox Portable can still receive updates just like the standard version. When an update is available, you can apply it to the version stored on your portable drive.

Use Cases:

Shared Workstations: Access your personalized Firefox on library computers, schools, or workplaces where you can't install software.
Privacy: Keep your browsing private by not leaving history or other data on the machine you use.
Customization: Take your customized browser, with all your settings and extensions, wherever you go.
