When I quote someone and type under the quote a few sentences, then for some reason I click in the quoted area (such as attempting to type above the quoted post) everything I've typed below the quote disappears and cannot be recovered. The Fire fox "undo" command does nothing. It is especially problematic when quoting a post with a link in it. I think this could be a bug. It is bad enough that I rarely use the quick reply when typing something I care about.
