Wikipedia:MozEx tutorial

This tutorial describes how to use the MozEx extension of Mozilla and Mozilla Firefox to edit Wikipedia pages in your editor of choice. Once MozEdit is installed, you need to configure the textarea setting to open up the text editor of your choice. One thing to note for Windows users, the path must not contain any "long filename" component. Instead use the dos mode. ("Progra~1" instead of "Program Files" etc.) For example: C:\Progra~1\editor\edit.exe %t. The '%t' is a required argument.

To edit a Wikipedia page, click on the "edit this page" tab. A box containing editable text will show up, which is sometimes called text area. Now, right-click with the mouse in the text area, and select mozex→Edit Textarea. Your favorite editor will pop-up, and you will be able to edit the text. Once you are done, save the text, go back to the browser window, and click on the text area. The text will be automatically updated, and the file you just saved will be deleted from your computer.
