Well. I think it is wery upset -- there is no way to do a focus to input text
without text to be selected. Following example created to show bug:

<form name="ThisForm">
  <input type="text" name="input_box" value="Entered text" size=55>
  <input type="button" value="Focus"
  <input type="button" value="Select"

Actions of buttons should be different, but they are same.

Reproducible: Always

Steps to Reproduce:
2.Click on "Focus" button to check that it do select() of input text
3.Click outside of text area to lost focus and clicl "Select" button

Actual Results:  
result of focus() and select() functions are the same

Expected Results:  
focus() should not select text in input area

This bug is not shown in Mozilla 1.0.0 under Linux from Debian distibution.
This was done on purpose, but I'm not sure the goal was to have .focus() from
user JS also perform a .select() (though it may have been).

It certainly seems rotten not to have any way to do this.  What do other
browsers do?

with IE 6, the buttons do 2 completely independant things:
- 'focus' moves the cursor to the left of the first character in the input.
- 'select' selects all the text and doesn't have a cursor (if you move left, the
cursor is to the left of the first character, if you move right, the cursor is
to the right of the last character.)

this bug causes problems in mozilla on pages that have a body
onload="form.input.focus();" because if you're typing when onload fires, you
lose all your input. 
OK.  I think one way to do this is that .focus() should focus the field and
select it _unless_ the field already has focus.  Then it should be a no-op. 
That should at least not select() the textfield you are currently typing in....
(we have bugs on that too; can't find the bug#s right now).

The other option is to differentiate clicking a text input from calling focus()
on it (and maybe have to differentiate whether focus() is called from chrome or
content too?  not sure what chrome expects here).

Notice that the comments in the patch for bug 28583 suggest that this bug is
_not_ an intended consequence...
This is aaron's.

Just one thing should be added. Right now there is no way to do a js deselect --
so if focus() call a select() then it would not possible to made an unselected
focus (well, I could think about hard-coded event emulation). So js focus()
should be different from chrome focus(). Other way is to add a non-standart
deselect() method for input.
chrome is written in JS.  So the deal with making chrome and content behave
differently (if we want to) will involve looking at the security context of the
JS in the usual way.

IE actually does a pretty cool thing that may be required to get focus() to not
interfere with your text while typing:  it remembers the cursor location.  it
seems to clear the location when the document has the focus.  so if you have
"text" in an input, and the cursor is between the 'e' and the 'x', focus() will
always put the cursor in the same spot unless you click on an empty area of the
document.  at that point it puts the cursor at the 0th position of the input.

I bring this up because if mozilla's focus() always puts the cursor at the 0th
position, searching amazon for "Simpsons" will result in a search for "psonsSim"
if you are typing when body.onload fires.

I cannot tell you people how many times my Google searches or Excite email
password entry get messed up now because of this bug.  Any progress?

The textfield should get selected when moved to via kbd, not from mouse click or .,focus() call

My mistake -- I originally thought it should get selected as long as it wasn't
focused via the mouse. Moving this into ChangeFocus() avoids calls that come
from script.
