I tried that but even that passes for me: [...] 11:14.08 /usr/bin/notify-send --app-name=Mozilla Build System Mozilla Build System Build complete 11:14.31 We know it took a while, but your build finally finished successfully! To view resource usage of the build, run |mach resource-usage|. To take your build for a test drive, run: |mach run| For more information on what to do now, see https://developer.mozilla.org/docs/Developer_Guide/So_You_Just_Built_Firefox
I don't see that bug any more, closing now.
