^ Since 12-4-15, 24 confirmed cases of Firefox 43-45 breaking El Capitan's shutdown & 2 reports for 10.6.8 (Snow Leopard).įirst reported on a Fx 43 beta build (Dec 4, 2015): Thanks to the feedback I found on Input, I was able to paint that timeline. > Is this for 45.0.1 only? Happening also on beta, aurora, nightly?įrom what I've been able to dig up, it looks like this bug started with Fx 43 and that 42 was unaffected.

(In reply to Liz Henry (:lizzard) (needinfo? me) from comment #7) But since the updater is mentioned, Rob Strong comes to mind. Tyler & Liz, would you be able to prioritize this bug and get the word out to the devs? I have no idea which devs specialize in mac shutdown code. That it can't be force quit in the Activity Monitor & the OS can't shutdown and kill the process blows my mind. Of all the problems I've witnessed in my ~11 years of Firefox support, this is the most insane and embarrassing bug I've ever seen. This sounds like a very severe regression to me so I'm marking this as critical. This bug appears to date back all the way to Fx 43 (Dec 2015):
