This add-on extension "Disconnect", after upgrading to Firefox 29 now displays only a tiny drop down box when clicked vs the full drop down menu. Before the upgrade it worked fine. It does this whether adding it to the tool icons in the upper right of the window (left of the new Firefox dropdown menu) or whether adding it to the Firefox menu itself as an additional icon. The extension appears to work in terms of blocking adds/tracking, as before, just can't see what is in the drop down menu. Already tried disabling and re-enabling, no change.
