Major Changes Since 1.13

Per-window private-browsing

This release of the SDK adds support for per-window private-browsing. See the private-browsing API documentation and this blog post for more details.

If your add-on uses private browsing and is built with an earlier version of the SDK, it must be repacked with this version to be usable on Firefox 20. We are aiming to automate repacks of as many add-ons as possible, and will contact the authors of AMO-hosted add-ons to let them know if they need to repack.

Due to a platform bug, if you update your code to use the new private browsing APIs (rather than just repack your code with the new SDK version), then your add-on will not be able to use the panel module.

Unique IDs for tabs

Tabs now have a unique ID: bug 795645.

Bug 627432

If your add-on stores data using the simple-storage API, the data is not cleaned up when your add-on is uninstalled.

Bug 571049

If an add-on is uninstalled while it's disabled, it's not notified of uninstall. If the add-on needs to do some special cleanup on uninstall, like removing persistent storage such as a file, this won't be possible if it has been disabled.

Bug 660862

By default, widgets are placed on the add-on bar, and given a height to match the height of that bar. If the user moves the widget to a different toolbar, and that toolbar has a different height, the widget's height is not updated accordingly.

Bug 660857

A widget containing HTML content gets no icon in the Customize Toolbar Window.

Bug 660860

When a user removes a widget from the toolbar its detach event does not get sent.

Bug 556562

If you have copy of mozrunner installed on your system, the cfx test command may not work correctly.

There is a workaround for this.
