EmbeddedEditor (Firefox Extension)


There are a few extensions that allow you to edit HTML textareas using external editors, but none of them embed your external editor directly into the web page. With EmbeddedEditor extension you just press Ctrl+E shortcut while editing an textarea and it will be replaced by your favorite text editor. After closing your editor, the textarea will show back with all the text written in the editor.

The EmbeddedEditor extension depends on mozplugger mozilla plugin. Therefore, you have to install mozplugger before installing the extension. The mozplugger can be found and downloaded from its homepage: http://mozplugger.mozdev.org/
