About importing and exporting Photoshop layer masks

In Photoshop, you can mask images using layer masks or grouped layers. Fireworks lets you import images that employ layer masks while retaining the ability to edit them. Layer masks are imported as bitmap masks.

Fireworks masks can also be exported to Photoshop. They are converted into Photoshop layer masks. If the masked objects include text and you want to maintain text editability in Photoshop, you must select Maintain Editability Over Appearance when exporting.
