Once connected on your WordPress blog, it might take some time to publish a new article.
Why not write if off-line and put it on your blog right after?
I have found quite a good Firefox/Iceweasel plugin which does the job well : Scribefire
The extension can be installed from the following link :
At the moment, it fullfills my needs. It can be launched in a new tab. You can add new categories right from this extension.
The editor is simple but functional.
However, I am not able to modify an article through it. Is this a missing function?

Feel free to send me feedbacks on your personal use of any of the existing off-line text editor extensions for Firefox/Iceweasel.
