Bug with close tab button in active tab Puntuado con 3 de 5 estrellas

When the option is choosed, that the close button should only appear in the active tab, there is no close button anymore!
When I switch to another close tab button position option (e.g. show on all tabs) and back to "show only on active tab" the close button is back on the active tab. But when I close the broser and reopen it there is no close button on the active tab again.

The other close tab button options do function (show on all tabs, etc.).

I am using Firefox 18.
