Question

I have this HTML code :

<ul class="navigation-links">
    <li class="link-item">
        <img src="images/new-menu/menu-item_04.png" width="150" height="41" alt="" />
        <div style="display: none" class="sub-menu">
            <div class="sub-col">
                <img src="images/new-menu/home.png" width="46" height="14" alt="" />
                <ul>

    <li class="link-item">
        <img src="images/new-menu/menu-item_02.png" width="152" height="41" alt="" />
        <div style="display: none" class="sub-menu index-menu-col3">
            <div class="sub-col">
                <img src="images/new-menu/lighting.png" width="35" height="16" alt="" />

          </div>
            <div class="sub-col">
                <img src="images/new-menu/electric.png" width="106" height="19" alt="" />
                <ul>
                    <li>item</li>

                    <li>item</li>
                    <li>item</li>
                    <li>item</li>
                    <li>item</li>
              </ul>
          </div>
          <div class="clear"></div>
        </div>
    </li>
    <li class="link-item"><img src="images/new-menu/menu-item_01.png" width="151" height="41" alt="" /></li>
</ul>

and this JavaScript code :

$(document).ready(function(e) {
$(".link-item").hover(function(e) {
    $(this).children(".sub-menu").slideDown("slow");
});
$(".link-item").mouseleave(function(e) {
    $(this).children(".sub-menu").slideUp("fast");
});

When I open this page on Firefox and try one of these menus, it will act very strangely. and the pointed menu will slide down and slide up continually.

It looks like you have some “empty” area right under your links that is causing the menu to go up and down. You could try moving the menu up so that that empty area isn’t moused over, which is causing the “mouseleave” function to be executed.
