querySelector[All] support landed just in time for Firefox 3.1 alpha 1.  This gives web developers a much faster method of getting the set of nodes matching a CSS selector, and hopefully tookits will pick it up and start using it so that web developers get the benefits transparently.  For those interested, there is a test put together by the Webkit developers that compares querySelectorAll performance to that of existing query mechanisms.

Mozilla’s David Baron recently posted about some new CSS features in Firefox 3, including

• inline-block and inline-table values for display
• rgba() and hsla() values for semi-transparent colors
• font-size-adjust for specifying font sizes by ex-height instead of em-height
• white-space: pre-wrap
• and some experimental new keywords for width, min-width, and max-width.
