[Project_owners] CSS urlbar

[joe ertaba]

Hi,

I used this css to hide and show my extension icon
#urlbar[a attrible is true] > #MyIcon
{
    visibility: visible !important;
}
#urlbar[a attrible is false] > #MyIcon
{
    display: none !important;
}

now I want to show my extension icon when mouse is over urlbar

#urlbar[a attrible is true] > #MyIcon
{
    visibility: visible !important;
}
#urlbar[a attrible is false] > #MyIcon
{
    display: none !important;
}
*#urlbar[a attrible is false]:hover > #MyIcon
{
    visibility: visible !important;
}*

it doesn't works :(
can anybody fix it ?
