User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20170905220108 Steps to reproduce: When I launch Nightly and click About, I see "Restart to update Nightly". Actual results: When I restarted Nightly, "About" still tells me to restart. In result Nightly is all the time in build from yesterday, 5th September, can't update to the latest build.
I restarted computer and updater could finally update Nightly.
This happened again. Nightly sometimes can't update and eventually restarting the computer fixes that.
