Am trying out Mozilla ComposIte with this post with Mozilla 1.1. Once the plugin is installed, with the cursor positioned in a textarea window (such as the story text form for submitting news at Kairosnews), hit "ctrl-e" and an HTML WYSIWYG editor opens up. After creating the text, hit "save," and the HTML is added to the textarea window. Great for Kairosnews posts.Seems to have a small bug with spacing words on ocassion, but otherwise, I like it! Get the plugin here. Make sure it's compatible with your version of Mozilla.
