We found the bug and fixed it. There should be an update soon. If you'd like fix it now, you can do this.
Follow the instructions on this page to create a userChrome.css file:

Then add the following to that file:
#main-window[btBoom="lookingforgroup"] statusbarpanel#statusbar-display {
-moz-appearance: none !important;
border: none;
}
Hope that helps!
