XKit version 7.2.1 is now available to download for Firefox users. It is highly recommended that you update to this version.

This version fixes the “$ is not defined” error (hopefully!). I apologize for the time it took for me to fix this, I always thought it was related to jQuery/DOM, just today realized it was related to network-related code.

It also fixes some of the less annoying/noticeable problems, such as the Storage panel under Others always showing that you use 0% of your storage.

To download it, just go to the Download page and re-install XKit. It will automatically update itself, preserving your settings.
