This has worked perfectly for many years, and has required no maintenance. Writing a piece of software so elegant and successful that it requires no updates over many years is like a hole-in-one in golf - exceedingly rare, and as an aspiration it is practically hubris, but when you finally see it, it is something to be celebrated. So, if the maint takes a little vacation, it is well deserved. Why hasn't mozilla just signed it? Who can say. Thanks, for nothing moz.
