Notes about the XPI file extension:

Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

The XPI file type is primarily associated with 'Mozilla/Firefox Browser' by Mozilla.

This is basically a ZIP file that, when opened by the browser utility, installs a browser extension.

To install a local version of the file, you can drag and drop the file onto an open Firefox browser window or use the Firefox File | Open menu command. In most cases the file will be downloaded via Firefox after you've searched for new add-ons and will, at that time, automatically install itself and be available after a browser restart.

This extension applies to both Mozilla and Firefox browsers.
