in Firefox 15, the checkboxes in the clear history window from the Tools menu are completely dead.
Update: I finally found the cause of the problem. The sanitize box apparently has a listbox, and the listbox.css file did not list any checkmark images, so they did not appear.
Thanks, I tested this and saw this as well - should be fixed in the new 2.13 version. Thanks!
