Like me, most people love to use Thunderbird at work instead of crappy Outlook. After all, Thunderbir is pluggable. Adding to the delight, here comes a hack to inject Google Wave into Thunderbird, so that you never stop collaborating.
How To:
Open Error Console window (Tools > Error Console) and copy/paste the following code:
Components.classes['@mozilla.org/appshell/window-mediator;1'].getService(Components.interfaces.nsIWindowMediator).getMostRecentWindow("mail:3pane").document.getElementById("tabmail").openTab("contentTab", {contentPage: "https://wave.google.com/wave/?nouacheck"});
When done, hit Enter. Now Google Wave tab opens up. Simply login and starting Waving.
Thunderbird 3 saves all tabs when closed, so you won’t have to go through the steps again when you start another session of Thunderbird.
