Just in case someone is in the same situation, as a temporal workaround I installed the kfirefox add-on (v 0.16) and now Biobar is fine, although the whole firefox appearance has changed a little bit, making it more similar to the original firefox theme, more than to the (k)ubuntu theme, which I like more.
