I’m trying to create a website for myself and just ran into this issue:

As you can see there is some kind of selection visible in both images which I don’t want to be displayed.
The first image is taken after I clicked the menu item.
The second image is taken after the first when I additionally move the mouse over it.
These menu items are shown in a table.
I am using FireFox 3.6.10.
Does anybody have an idea how to get rid of these selections?
Check out the
outlineCSS property. You should specifyoutline: nonefor your links in this case. The outline indicates that the given element has focus. You should provide something instead to make keyboard-only navigation possible.
