About this add-on

This extension is a more advanced version of the OPIE (Ordered Preference Import/Export) extension. It allows for the import/export of any installed add-on's preferences. This is useful when installing extensions in a new profile, or synchronizing multiple Pale Moon installations.

Preferences are initially determined by OPIE2 by searching about:config for the most likely entries. The user can add/remove any or all of these preferences from the assigned list. OPIE2 also allows for the creation of user-defined preference packages that don't necessarily belong to a specific extension but are used to create a particular browser environment (i.e. for developers).
