Since Mozilla announced Mozilla Persona as Mozilla’s offering for all online identity related services and technologies, it has also decided to rename former Firefox personas (images used as toolbar backgrounds) to background themes.
The move attempts to label the feature with a more descriptive name (something personas never really did), and serve as an introduction to Firefox’s complete themes, the ones we currently know and involve modifying icons, widgets and text in addition, at the same time.
While reusing a term within any ecosystem is an obvious formula for confusion, Mozilla is pretty confident the risk of it is worth the gain in simplification for future users of the feature and Mozilla’s identity system.
By the way, have you checked the
personas background themes section in Mozilla Add-ons, lately? It has grown a very large collection of beautiful pieces to suite your taste and mood.
