It's been a long time since I created a background theme. Last I knew, Mozilla stopped accepting new animated themes, because they caused the browser to run slower, which tended to create bad publicity in speed tests. Mozilla's tendency to continually mess around with & dramatically change browser layout capabilities has created an unpredictable layout that adversely affects the appearance of designs. Because of this, I became frustrated & lost interest in continuing to design background themes. Many of my themes no longer display as originally intended, and so I spend my time on other things that are more rewarding. I appreciate your positive feedback though, so thanks for letting me know.
