File Extension XPI

File type: Extension Archive

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.

When windows gives you an error message saying that it
"Cannot open XPI files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

In both cases it is strongly recommended that you
run a free scan for registry errors.
