 Cookies control access to **local storage** and **indexedDB**. The `ghacks user.js` denies cookies by default. This is the pref `network.cookie.cookieBehavior` (see `2701`). A value of `2` denies all cookies, a value of `1` allows first party only.

+`Pro Tip`: If you are not sure what extensions require IndexedDB
+  * enable first party cookies in your `user.js` and restart
+  * check the options (if any) for each extension
+  * look in your `profile\storage\default` directory for `moz-extension` entries (see pic 1)
+  * add these entries manually via the cookies exceptions dialog
+     * just replace `+++` with `://` (see pic 3)
+     * directory: `moz-extension+++e0cc77c6-3785-4297-a034-7896f46563af`
+     * exception: `moz-extension://e0cc77c6-3785-4297-a034-7896f46563af`
+  * set cookies in the `user.js` back to none and restart
+  * clean out any unwanted cookies and storage collected during this exercise
