I finally got around to checking out the Firefox extensions that have come out in the last month and all I have to say is wow.  Two of them really jumped out Xinha Here and Spellbound which together add up to being a very nice word processor.  Xinha is a nice chrome app  that enables WYSIWYG editing in any html textarea and text input elements. Selecting "Xinha Here!" in the context menu opens Xinha editor on the client side. This allows you to edit the fields data in a WYSIWYG on any website without coping and pasting to secondary editor.  Spellbound is a spell checker that  enables spell checking in web forms such as html textarea. 

 Having used Xinha and Spellbound on Windows, Linux and MacOS X I have to say that it operates as fast as a desktop app and has enough features that I can use Xinha and Spellbound with my various  CivicSpace sites and not really need to use typical word processors very much or if at all.   

I should add that you have to install Xinha and Spellbound you have to flag both websites as being allowed to install extensions into Firefox and that Spellbound requires several steps, check out the above URLs for instructions.
