A note for those early-adopters enjoying Firefox 3:

Firefox 3 has a bug that caused Add to Any’s drop-down menus to vanish when you move the mouse rapidly over the menu.

Luckily, we found a workaround to this problem and have updated the drop-down menus.

For those interested, the bug is exclusive to Firefox 3 up until at least yesterday’s nightly release. Thanks to PD for reporting the bug to us and Mozilla.
