We wanted the Evergreen staff client for PINES to be built on a platform that was powerful, cross-platform, standards compliant, and suited for RAD. To this end, we settled on the Mozilla framework. Some applications that use this platform include: Firefox, Thunderbird, and Sunbird. We test the staff client on Firefox, Mozilla, and XUL Runner. Starting with our Alpha release, we have been bundling the staff client with XUL Runner as a single executable installation file.
