Hotfix updates to 1.13

The 1.13.1 release is a hotfix release that replaces the 1.13 release. It includes the following extra fixes:

  • bug 836318: reverted context menu items in sub-menus to display by default as they did in 1.12
  • bug 832401: fixed an issue where certain combinations of add-ons could result in an extra separator in the context menu

  • bug 836061: fixed simple-storage and other modules when run against Firefox 21

Major Changes Since 1.12

Context-menu rewrite

We've rewritten the context-menu module, bringing the code up to date and fixing a number of bugs, including:

Translators key supported in package.json

The package.json now enables an add-on author to list the translators of an add-on, and these are translated into "translator" elements in the add-on's install manifest. Thanks to community contributor CIAvash for this.

Unique IDs for tabs

Tabs now have a unique ID: bug 795645.

This feature was originally announced as being in the 1.13.1 release, but actually won't be available until the 1.14 release.

Bug 663048

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 661884

Selection events for a page are not sent if the page did not fully load (for example, because the user stopped the page loading).

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.
