I have been using this extension for quite a while now. What does it do? You can edit browser textareas using an external editor of your choice. As a web developer this has proven indespensible for me and i even waited to upgrade to Firefox 2, until someone came down with an upgraded version of this sweet little addon.
Now with the release of Firefox 220.127.116.11 it was outdated again, and noone has posted a new version yet. Simple things are so easy, so i extracted the whole thing and simply changed the version number in the install.rdf.
Happy to share this with the you through rapidshare: http://rapidshare.com/files/10914171/
