After some investigation about possibility to make the Online editor work for Mozilla, we found that dhtml component in midas is not as good as IE, especially it is impossible to select and edit properties of every input tag which makes it is not so useful for eZ publish. ( we support attribute 'class' in 3.1 for almost all input tags and editing this property should be supported in editor). It also lack necessory functionalities for table editing. Since midas API is still in its developing stage, we may make Mozilla editor when it is mature enough.
A true xml editor is the way to go (keeping an eye for the bitflux editor, part of the lenya-apache CMS), as one day ez publish should support more xml variants.
eZ systems, don't let lenya (or any other cms for that matter) do catch up with ezp ;-)
As much as I dislike lenya and its screwed UI (which is, BTW, from what I know, a project mainly by my Uni, they use it for a lot of their publishing stuff at least), in one place they have far surpassed ezpublish: performance. lenya is seriously much faster than ezpublish. Thinking of it, the BIGGEST trouble with ezpublish IS speed...
