Mozilla prepares coders for Firefox 4 features

The proposed IndexedDB standard, which provides a local database store for Web applications, will be supported by Firefox 4.

It was with delight that I read these words on Thursday: "The proposed IndexedDB standard, which provides a local database store for Web applications, will be supported by Firefox 4."

The statement appears on Mozilla's new Firefox 4 for developers site, boding well for those of us who use the Web a lot: the IndexedDB interface gives Web applications a way to work even without a network connection.

The proposed IndexedDB addition to the HTML standard is one of a collection of technologies opening new horizons for Web programmers and putting competitive pressure on Adobe Systems' Flash Player plug-in. The main reason I'm interested in it in particular: the restoration and, I'd hope, improvement of Google Docs offline access and editing features. But I could see it as improving performance for some Web sites, too, through more sophisticated caching, for example.
