Fix scrollbar issue in FF15 Rated 5 out of 5 stars

To fix scrollbar problem, replace the the following content in scrollbars.css inside the foxdie.jar.

By the way, don't forget to change same properties for horizontal scrool bar just below the same code.

-- before --
thumb[orient="vertical"]{
position: relative;
min-height: 24px;
width: 15px;
-moz-border-image: url("chrome://res/skin/aqua/scrollbar/thumb-v.png") 12 0 / 12px 0 repeat;
}

-- after --
thumb[orient="vertical"]{
position: relative;
min-height: 24px;
width: 15px;
border-width: 12px 0;
border-style: solid;
border-image: url("chrome://res/skin/aqua/scrollbar/thumb-v.png") 12 0 fill stretch stretch;
}
