How to Update Extensions to Firefox 3

By Adam DuVander July 21, 2008 Categories: Uncategorized

FirefoxIf you’re a Firefox extension developer who hasn’t made the switch to Firefox 3, Mozilla wants you to know what you need to change. On the other hand, if you have a favorite extension stuck in Firefox 2, you might pass this article along to its developer: Mozilla’s instructions for updating extensions for Firefox 3.

There were a number of changes between Firefox 2 and 3. The largest changes are outlined in the document, which include:

  • Bookmarks and history - major changes, now uses Places API
  • Anything using menus - heavily modified
  • Download manager - now uses Storage API
  • Password manager - now uses Login Manager API

Extensions that don’t utilize above areas of the code may still need tweaks, but may not require major rewrites. You may even get lucky and just need to change the maxVersion of your extension. If Mozilla hosts the extension for you, then you won’t even need to change anything in the extension itself. Just login to the addons site and use the Developer Control Panel to make your maxVersion 3.0.*.
