There is no space on the reporting form to enter keywords. In addition, the instruction page on when and how to report a bug does not mention adding them, even for regressions, although they list regression procedures (e.g. attaching regression test). I will do it in the future.
My apologies, seems that option's not enabled for unprivileged users. See bug 17074.
