Very convenient. I am using it for web-apps (time-report, calendar). It has good settings too, so if you are like me, and prefer opening regular weblinks in your regular browser, you can have it that way. Opening specific links only in a thunderbird-tab (like the mentioned web-apps) is still very easy, just right-click a link and choose "open link in new tab".
