Geek to Live: Turn Firefox into a web writer - Lifehacker *
The rise of the read/write web makes the term “browser” a misnomer. If you use web-based e-mail like Gmail, or if you post to forums or write a blog, you’re using a “browser” to author documents as well as browse them. A plain, tiny web page textarea is not very conducive to writing. If you spend a lot of time writing the web with Firefox, soup up your “browser” with a few extensions that will turn it into a powerful text editor.
