I think we did it to give form controls focus in the newly loaded webpage. A lot has changed with focus since then. Maybe we can remove it.
Alternatively, there are ways to focus that content without raising the window (focusing the <browser>, I think?)
The flag didn't do it...

Is there any cases where we want Fennec to raise when we call focus()?

Otherwise we could default mozilla.widget.raise-on-setfocus to false
Ever confirmed: true
We don't want to change window.focus() behavior across the board, we just want to avoid calling it in that case. The question is whether we need to replace it with something else... what breaks if we just remove it?
Attached patch patchSplinter Review
This patch simply removes the code the explicitly focuses the dom window. We originally did this to work around web content focus problems. For example, when loads, it focuses the editbox. Fennec was not allowing that to happen, so we added this code.

The focus code in gecko has been overhauled since then. I removed the code and the editbox at was focused (and yellow) after loading. I could also start typing into the editbox with needing to tap it.

Loading (or other large web site), then switching apps did not force fennec to pop back when the page finished loading.

Score this one to Neil Deakin!
