I’ve posted workarounds before to make the Firefox Blog This plugin for Windows Live Writer work for Firefox 3.0 and later. Now we’ve finally taken the first (public) steps to solving this problem the right way.
Our revised extension is now available on addons.mozilla.org. We’re currently in their “Sandbox” which means you will have to log in to download the extension. After enough people download it and write reviews (please!), we’ll be allowed to nominate the extension for graduation from the Sandbox. At that point we’ll take down the older version of the plugin from gallery.live.com and announce the new plugin on our team blog.
By the way, there is no new functionality in this version, other than an updated (Windows Live 2009 style) icon.
Sorry for making you wait for six months for this. Our (and especially my) bad!
