i don't really like either 'fix'.

one gags on FF ( mine with break-word. yes, break-all was wrong )
the other gags on wide screens by limiting width, so any fluid themes suffer.

this really points to getting away from table,tr,td, where stretching isn't always a good thing. td's are notorious for being fickle on variable widths and their containing items don't play well..

drupal has a thread dedicated to just this issue and they say they 'solved it' and even committed the changes, but it didn't...
