There is a good chance this is a duplicate of bug 1370576 which also fixes bug 1368600. After updating Firefox to the next nightly please comment in this bug as to whether it is still happening. Thanks! Bob (Reporter) Comment 4 • a day ago Just had nightly inform me of an update clicked the download button While this was happening daily informed me that update was available Waited until I thought nightly update had down loaded closed nightly Started nightly it did not load Clicked the update button on daily then the restart button daily did not load Started task manager neither nightly or daily apps loaded Checked background processes Found a daily and a daily update process Ended daily process and daily immediately loaded Found 4 nightly process ended the 4 then clicked to start nightly it loaded correctly Checked help about nightly found there was an update 19 June available Clicked to download then clicked to restart it did not load Checked task manager found 5 background process Ended 2 and nightly immediately loaded Checked task manager nightly and daily had apps loaded Nightly had 6 background process and daily had none Checked update status both up to date Both programs working OK Robert Strong [:rstrong] (use needinfo to contact me) Comment 5 • a day ago Thunderbird hasn't made the change that Firefox has (a Thunderbird dev has been informed) so lets keep this to being about Firefox. Firefox has a 63 second timeout before it kills itself when exiting so an update can be applied. During the next update please wait a couple of minutes and hopefully that will provide more details to go on. Thanks! Bob (Reporter) Comment 6 • 23 hours ago Have just checked task manager again Did the above steps at approx 0300 and it is now 0620 WST Australia and nightly has 10 background process will wait as requested next update Robert Strong [:rstrong] (use needinfo to contact me) Comment 7 • 23 hours ago The number of processes when running Firefox has nothing to do with updating. This is how Firefox works now that it has support for multiple processes. That info *might* be of value when it doesn't startup correctly but this info definitely doesn't provide anything of value when running normally.
