In FF3, highlighting multiple paragraphs does not work.
Duplication Steps:
1. In normal view, type anything then hit <enter> then type some more
2. Select all text and choose to highlight
3. Notice the text has not been highlighted
Try changing the font, notice the same problem of nothing working. I'm sure this problem extends to almost everything, so please look for them all without needing them explicitly stated.
It has been replicated on your own site.
