The use of this attribute on a
<button> is nonstandard and Firefox-specific.
The use of this attribute on a
<button> is nonstandard and Firefox-specific. By default, unlike other browsers,
Firefox persists the dynamic disabled state of a
<button> across page loads. Setting the value of this attribute to
off (i.e.
autocomplete="off") disables this feature. See
bug 654072.
This Boolean attribute lets you specify that the button should have input focus when the page loads, unless the user overrides it, for example by typing in a different control.

This value is the default if the attribute is not specified._blank: Load the response into a new unnamed browsing context._parent: Load the response into the parent browsing context of the current one. If there is no parent, this option behaves the same way as _self._top: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.
