Terrific Rated 5 out of 5 stars

Best WYSIWYG / HTML editor extension I can find (and man have I looked) . Great for taking notes in HTML or just text, also useful in creating pages or posts for blog. and its simple and elegant.

To open the editor initially you must find a Text Field (even a password box or comment form will do). right click and choose the mode you want from the context menu.
I always chose the window version. The split screen version does not let me copy/ paste, but the editor in the window selection works great.

only complaint is that if I have "hyperlink" text, I have to type the URL in by hand, Can't Copy /Paste into the add URL box.

Otherwise its terrific and essential.
