nsIMutableArray
xpcom/ds/nsimutablearray.idlscriptable this interface is a subclass of nsiarray that provides arrays that are mutable; that is, they can be altered programmatically.
... inherits from: nsiarray last changed in gecko 1.8 (firefox 1.5 / thunderbird 1.5 / seamonkey 1.0) consumers of nsiarray should not queryinterface to nsimutablearray unless they own the array.

XPCOM array guide
nsimutablearray - a scriptable container for scriptable xpcom objects, which allows addition and removal of member objects.
... ownership nsiarray xpcom object yes no no no reference counted, weak/strong nsimutablearray xpcom object yes no yes no reference counted, weak/strong nscomarray<t> xpcom object no yes yes* no reference counted, strong nstarray<t> any that has a default constructor and copy constructor no yes yes* no can hold objects directly, in which case it owns them.

nsIArray
for an array which can be modified, see nsimutablearray.
...it is also convention that if an interface provides access to an nsiarray, that the array should not be queryinterfaced to an nsimutablearray for modification.
... if the interface in question had intended the array to be modified, it would have returned an nsimutablearray!
... see also nsimutablearray ...

AsyncTestUtils extended framework
xpcomhdrarray [getter] return an nsimutablearray of the message headers that have been injected into folders.
... folderswithxpcomhdrarrays [getter] same as folderswithmsghdrs but the second element in each sub-list is an nsimutablearray instead of a js list.

Address Book examples
addressbook.modifycard(card); deleting contacts once you have obtained a card(s) from an nsiabdirectory (see above) you can delete one or more simply by calling the deletecards function: let cardstodelete = components.classes["@mozilla.org/array;1"] .createinstance(components.interfaces.nsimutablearray); cardstodelete.appendelement(card); // repeat append as necessary addressbook.deletecards(cardstodelete); how do i add and use my own properties?
