css style pageBreakBefore problems (in Firefox)

[jman]

i'm printing a bunch of DIV elements.

i don't want any individual DIV to be split across a page.

i added pageBreakBefore="always" and each gets printed on a new page -
fine!

but ideally i'd like to force a new page, only if a DIV element does
not fit at the
bottom of the current page.

pageBreakBefore="auto" does not seem to do the job.

help!
