I believe Firefox 3's offline storage support is also HTML 5-compatible.

An alternative would be to use a framework that supports multiple storage
providers, such as Dojo Storage.

http://manual.dojotoolkit.org/WikiHome/DojoDotBook/Book50

"Right now the dojo.storage system includes three storage providers, a Flash
Storage Provider that uses a hidden Flash applet; a WHAT WG Storage Provider
that uses native client-side storage abilities in Firefox 2; and a File
Storage Provider that uses the native file system if a web app is loaded
from the local file system."
