The ninth beta version of Firefox, due imminently, is set to get support for a standard called IndexedDB that provides a database interface useful for offline data storage and other tasks needing information on a browser's computer.

"IndexedDB allows Web apps to store large amounts of data on your local system (with your explicit permission, of course) for fast offline retrieval at a later time. We're hoping that Web mail, TV listings, and online purchase history will one day be as convenient to access offline as they are online," Ben Turner, who develops IndexedDB for Mozilla's browser, said yesterday in a blog post.

Firefox 4 beta 9 has been built, is being tested, and should become available soon. After that Mozilla presently plans to ship a 10th beta, release candidates, and a final Firefox 4 version in February.
