Our long-term plans for Pale Moon involve (potentially) moving our browser to the UXP (Unified XUL Platform) that is currently being worked on alongside the browser. This will at its earliest be somewhere in 2018.
Plug-ins
Pale Moon supports NPAPI plug-ins. Unlike Firefox, we will not be deprecating or removing support for these kinds of plug-ins. This means that you will be able to continue using your media, authentication, and other plug-ins in Pale Moon like Flash, Silverlight, bank-authenticators or networking plug-ins for specific purposes.
