The issue I'm having with Nightly for the last few days, starting from Nightly 71.0a1 10/20/2019,
is that the updates are not actually get applied and it continually prompts to apply an update after browser restart

STR
Using win10 x64 version 1903
Nightly version 72.0a1 (2019-10-23) (64-bit), fresh profile.

• either: click 'Menu' icon|Help|'About Nightly':
  the browser automatically starts downloading the update (update size is 6.2 MB)
• or: just click the 'Restart to update Nightly' entry prompt displayed on the Menu button
• restart browser
• notice that the update was not applied:
  If I open Help|'About Nightly' it still downloads again the same/today's update (supposedly 2019-10-24),
  and even if don't do anything, I I'm constantly getting the prompt to 'Restart to update Nightly'
• At some point, that I can't tell what specific (sometimes it's after windows restart I relaunch Nightly, or maybe after a random UAC prompt appearance by Nightly), then the update gets applied. But even so, the issue always re-occurs with the next day's update: it has been happening to me in every single day starting from 2019/10/20 up today.
  There's no entry in about:crashes nor any relevant entry in windows Event Viewer.

I'd like to add that I've also tried uninstalling Nightly, removed previous profile and created a new one,
but the issue still occurs: it has been happening today, with my fresh Nightly installation being of 2019-10-25
and the 5.7 MB update doesn't get applied after multiple browser restarts. Eventually, after maybe the 5th browser restart , it downloaded a 53.9 MB update and and I got this message (see attached screenshot):

"Nightly can't update to the latest version.
Download a fresh copy of Nightly and we'll help you to install it"

Same here for some time, downloading full version does not help. Look like something corrupted in profile.
What logs I can collect to debug the issue?

Today the following occurred:

Nightly was of 2019-10-27.
I clicked: Help|'About Nightly', the browser started downloading the update (6.8 MB). Once again, after browser restart the update was not applied.
Then I clicked "Help|About Nightly", it remained(=kept on checking) at "Checking for updates", and so I closed the "About Nightly" window a few seconds later. Shortly after, I closed Nightly.
I launched Nightly again some time later, and I immediatelly got a UAC prompt (see attached photo),
I clicked "Yes" and then the update was applied ok, i.e. Nightly got updated to 2019-10-28.

Just one thing to add:
the issue only occurs with Nightly - it does not occur with my Firefox stable installation: just now it updated ok from 70.0 to 70.0.1 .

Comment 6

The issue still occurs for me.

Is there any info I can provide to help identify the cause of this issue?

I seem to be having the same issue on my Nightly on Windows 8.1, for several weeks now.
Please let me know if there's any information I can provide to help.

[Kostas]

The issue no longer occurs, it's about 10 days now. (I hadn't changed anything in the Nighly installation, i.e. no re-installation or fresh profile creation).

Alexander Usyskin and Adrian Wielgosik, if that's also the case for you, please tell me so that I'll close this bug.

Yes, last week updates are successful, no change from my side in profiles. Go figure...

This is most likely due to the same underlying cause of bug 1596778 since this is no longer reproducible so duping
