User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36
Steps to reproduce:
With a document as follows:
<!DOCTYPE html>
<html>
<body>
<div contenteditable="true">Test <a href="#">selection</a></div>
</body>
</html>
I obtain the two IAccessibleText objects as:
iaText1 (which has the text "Test \uFFFC"), and
iaText2 (which has the text "selection")
I want to create a selection from an offset in iaText1 to an offset in iaText2:
iaText1.setSelection(0, 2, IA2_TEXT_OFFSET_LENGTH);
iaText2.setSelection(0, 0, 3);
Actual results:
I end up with only "sel" in the selection.
Expected results:
I want "st sel" in the selection.

You can do this with:
iaText1.addSelection(2, IA2_TEXT_OFFSET_LENGTH);
iaText2.addSelection(0, 3);

Calling addSelection twice creates a multi-selection. I guess I forgot to specify that I needed to be able to create a single selection, this is because many editors (i.e. Gmail's compose) don't expect multiple selections and don't handle them well enough.

When you say multi-selection, are you saying it's represented as if it's non-contiguous? I think Firefox should really merge the two selections when addSelection is called the second time, since as far as IA2 is concerned, the range is contiguous.

I think this is doable. Btw, is it a big concern from AT perspective?
Thanks James, I think that's a sensible solution.
Yes, for voice to text it's important to be able to say "select xyz", and have that selection contiguous so that it can then be edited by voice, or via keyboard.

This, along with several other problems, has been solved in a much better way using the (relatively recent) IAccessibleTextSelectionContainer interface. I implemented support for that in bug 1846660.
