UXP has been released to the community for maintenance and coordination to continue building on where desired. In addition, our platform code has been changed to a more streamlined version over the past months and UXP is no longer used (or maintained) by us in this milestone. Please note that our current add-ons site will, for a while, serve both older versions of Pale Moon and newer ones in a side-by-side manner, and it is important that you do not spoof your user agent when visiting the add-ons site or you may be served the incorrect type of add-ons or add-on updates, or not receive them at all. Please understand that this gives more freedom for people to use potentially incompatible and old/insecure browser extensions, but also means we will have a more 'hands-off' approach to it from this point forward which as a consequence means you will have to resolve more issues yourself and take more care, especially when using external/old extensions. Many customization and configuration optionsįollowing the change in direction as announced on the forum and directly driven by user feedback and community input, Pale Moon is abandoning its own GUID (globally-unique identifier) and adopting Firefox's GUID instead to provide maximum compatibility with old and unmaintained Firefox extensions alongside those that are maintained on our add-ons site.Extensive and growing support for HTML5 and CSS3.Support for a growing number of Pale Moon exclusive extensions.Increased stability: experience fewer browser crashes.
