1387124 - Firefox Installer.en-US launches Nightly without asking

Status: RESOLVED DUPLICATE of bug 1373244

(Firefox :: Untriaged, defect)

Description

[Mark]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20170803100352

Steps to reproduce:

Today, on page https://www.mozilla.org/en-US/firefox/channel/desktop/ in the "Nightly" section I clicked on the green "Download" button. This downloaded Firefox Installer.en-US.exe to my PC (Windows 7 Home Premium SP1 (64-bit)).

I opened the download directory and double-clicked on Firefox Installer.en-US.exe to run it, and clicked on the Windows confirmation that it was ok for the program to change files.

The installer ran.


Actual results:

When the installer finished running, it automatically launched Nightly, and Nightly used my default (54.0.1) profile.


Expected results:

The installer should have ASKED if I wanted Nightly to launch.

Asking if I want it to launch would have given me opportunity to modify the Windows shortcut to the program to include the recommended parameters of:
  -P "Test_Nightly" -no-remote
after the path and name of the executable in the "Target" of the shortcut.

Note that installer firefox-57.0a1.en-US.win64.installer.exe (from the "Channels" page linked above, clicking on "All languages and builds", and picking English(US) Win64) DOES ask the essential questions:
1. Use Nightly as my default browser, and
2. Launch Nightly.

Note: because of the change of location of FavIcon storage, this causes the FavIcon display in the Bookmarks to be permanently broken in the Default Profile if the Default Profile is also used for the Release Chanel version of Firefox.

Shouldn't the installer ASK before launching Nightly? But 1373244 doesn't mention anything about the installer ASKING if it should launch the installed program.
