== Removed in Thunderbird 67 ==
A major backwards-incompatible change was made to importing javascript modules. Where once you used any of these:
<source lang="javascript">
Components.utils.import("resource://foo/modules/Foo.jsm");
// or…
Cu.import("resource://foo/modules/Foo.jsm");
// or…
ChromeUtils.defineModuleGetter(this, "Foo", "resource://foo/modules/Foo.jsm");
// or the two-argument variation:
var { Foo } = Cu.import("resource://foo/modules/Foo.jsm", null);
// or…
var scope = {}; Cu.import("resource://foo/modules/Foo.jsm", scope); // scope.Foo…
</source>
You should now do this:
<source lang="javascript">
var { Foo } = ChromeUtils.import("resource://foo/modules/Foo.jsm");
// or…
var scope = ChromeUtils.import("resource://foo/modules/Foo.jsm"); // scope.Foo…
</source>
ChromeUtils.import is a replacement for Components.utils.import (which was also changed) in this way. Note that no second argument is supplied. The returned object is a dictionary of only the objects listed in EXPORTED_SYMBOLS.
