Mozilla said that this release will focus on HTML5 enhancements, giving us the feeling that the silent update feature will be pushed to version 11.
Another much anticipated feature is not mentioned either - a tool that would automatically import Chrome bookmarks and settings to Firefox. It appears as if this feature will also not surface until version 11 - and is even mentioned as "at risk" for version 11. These two features, as well as a the new home tab (also marked as "at risk" for version 11) are features that Firefox would have needed need yesterday rather than tomorrow to be able to be more competitive with Chrome. At least the silent update support is a must-hit target for version 10.
If you're feeling a little adventurous, but not too much, then check out the download for Firefox 9 beta here.
