Is there a good way to store an extensive amount of data when using Greasemonkey 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.

  • There's also a library for Greasemonkey that allows the persistent storage of Javascript objects across multiple domains: see here. http://userscripts.org/scripts/show/107941 – Anderson Green Dec 20 '12 at 03:48

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).
