Global variables with the same name as window properties can’t accessed. If you define a global in the window scope that has the same name as a window property (like name), you will run into this bug. This was caused by bug 932322. As always, we recommend good namespacing when defining globals.
Remove superfluous __SS_tabStillLoading property. This temporary property is used by a couple of add-ons but is going away. The bug includes possible alternatives.
Warn for showModalDialog uses. This only introduces a console warning, but you should keep in mind that this is deprecated now.
ignoreAbsent flag for removeDir() doesn’t default to true. This is in the OS.File library, in case you use it.
Rework DeferredTask to allow asynchronous tasks. This only affects you if you use the relatively new DeferredTask module.

New!

Add console.assert. A new logging option that takes an assertion as first argument and the log message as second argument.
Introduce a common JS Assert library. This introduces a new JS module that implements the CommonJS Unit Testing specification.
Introduce Session Restore API for global data. This introduces a non-window, non-tab specific session store.
