I noticed after the update that every time I terminate Nightly, I see a window (Command style window) created for Pingsender.exe, a program that appears in today's Nightly directory and also in the Firefox Developer Edition (Aurora) directory, but not in the Firefox directory. I don't see it run when I terminate the Developer Edition, but it does seem to consistently run when Nightly terminates. Anyone know what this is?</div><div id="yui_3_16_0_ym19_1_1493680312377_6133">--Steve Rovinsky<br></div><div id="yui_3_16_0_ym19_1_1493680312377_5807"><br></div></div></body></html>
