Storing data when using Greasemonkey

Is there a good way to store an extensive amount of data when using Greasemonkey开发者_如何学编程 for when GM_setValue just doesn't cut it?

Well here are the options:

1. Setup a server to save the data for the user, and use xhr to create/edit/remove data (Google App Engine (GAE) offers a lot of free storage space).
2. Use Web Storage which is implemented in Firefox.
3. Use Flash Local Storage.
4. Wait until Web SQL Database is implemented in Firefox..
5. A mixture of all of the above.

If you write a Firefox extension (or in the future you could make a Jetpack and use the Page Mod JEP 107 which is being developed) then you can also read/write/delete files to the HD.

use Lubemonkey found on Gamecore.org, works the same as greasemonkey (even the same commands) but you can store the data in an sqlite database using pure SQL (insert,update, selects , joins etc).
