Last night, Jorge Villalobos as Mozilla reviewer approved the 1.0 version of Write Area as an update, so now you should start getting update notifications for this version.
What do you get with Write Area 1.0?
With Write Area you can use the best WYSIWYG web editor inside your Firefox: in any site that allows to input HTML, either with a textarea or even from other not-so capable editors, you can launch Write Area using the context menu and that way you'll get full editing capabilities.
This version has been adjusted to avoid the existing problems with Firefox 4, so the upgrade of Firefox should not cause you any trouble. Some other details have been improved like focusing existing instances.
The internal editor core has been changed from the old FCKeditor 2.6 to the latest CKEditor 3.5, so future upgrades should come out sooner now that the used editor is again one under very active development. Nevertheless, updates in an extension requires review by a AMO editor, so instead of releasing an upgrade with every CKEditor release I might publish a "beta channel" version for minor updates and a full one where there's a new milestone or some important bugs fixed.
Besides that, you can keep using the internal Firefox spellchecker in a normal installation of CKEditor if you install the Gecko SpellChecker plugin.
Go ahead, click and install this extension.
