Mozilla doesn't adjust the status bar automatically however. This attribute serves only as a place to keep the text.

This can be used instead of setting the tooltip to a popup for the common case where it contains only text. The tooltip is displayed in a default tooltip which displays only a label, however the default tooltip may be changed by setting the default attribute on a <code><a href="/en-US/docs/Mozilla/Tech/XUL/tooltip" title="tooltip">tooltip</a></code> element.</dd> -</dl> -</div> <div id="a-top"> - - -<dl> - <dt><code id="a-top"><a href="https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XUL/Attribute/top">top</a></code></dt> - <dd>Type: <em>string</em> (representing an integer)</dd> - <dd>For elements placed directly within a <code><a href="/en-US/docs/Mozilla/Tech/XUL/stack" title="stack">stack</a></code>, specifies the pixel position of the top edge of the element relative to the top edge of the stack.</dd> -</dl> -</div> <div id="a-uri"> - - -<dl> - <dt><code id="a-uri"><a href="https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XUL/Attribute/uri">uri</a></code></dt> - <dd>Type: <em>string</em></dd> - <dd>For template-generated content, the attribute should be placed on the element where content generation should begin.

Usually, you would only use this on the <code><a href="/en-US/docs/Mozilla/Tech/XUL/window" title="window">window</a></code> element or other top-level elements.
