When I try to use the customize feature for toolbars, the toolbars themselves disappear as soon as I click "customize." This happens whether I choose "customize" from the drop-down menu, or use the "control-click" option. I don't remember having this problem before, since I've customized the toolbar previously, although not for a while. I'm running Firefox 17.0 on an iMac with OS 10.6.8
