Firefox is the default browser for all users

Hello,
I'd like to set up a package that restores Firefox as the default browser for all users on a computer.
After some research and testing on one machine, the most effective command seems to be
`C:\Program Files\Mozilla Firefox\uninstall\helper.exe /SetAsDefaultGlobal`.
So I created a package that runs this command with:
`run(r'C:\Program Files\Mozilla Firefox\uninstall\helper.exe /SetAsDefaultGlobal')`.
However, it seems to work on some machines but not others.
After investigating, I suspect it's related to User Account Control (UAC).
I therefore modified the registry before running the command, but it appears that a restart is required for the command to take effect.
My question is: I plan to create two packages: the first disables UAC, and the second restores Firefox as the default browser. How can I ensure a restart occurs between the installation of the two packages?
Thank you
, Matthieu

Good morning,
Here are the commands to integrate into your setup.py to do this:
For x64 systems:
Code: Select all
"C:\Program Files (x86)\Mozilla Firefox\uninstall\helper.exe" /SetAsDefaultAppGlobal
For x86:
Code: Select all
"C:\Program Files\Mozilla Firefox\uninstall\helper.exe" /SetAsDefaultAppGlobal
To help you build the script, you may need the functions below:
Code: Select all
makepath(programfiles32,'Mozilla Firefox','uninstall','helper.exe')
As well as the example below for concatenating and running the command
Code: Select all
command = r"powershell -NoProfile -NoLogo -NonInteractive -Command import-startlayout -layoutpath screenlayout.bin -mountpath "
path = os.path.normpath('C:\\')
commandsm = ''.join([command,path])
run(commandsm)
Problem observed:
Some Windows updates reset Internet Explorer to default
So, a word of advice: create this package independently of the name, using `tis-firefoxdefaultall`, and place it as a dependency on the main Firefox package
Because this way, to restore Firefox to default, you just need to regenerate a version of tis-firefoxdefaultall which will restore Firefox to default without reinstalling Firefox.

THANKS,
I'll be back with several tests.
If I understand correctly, this is what I need to write in the package:
Code: Select all
commande = makepath(programfiles32,'Mozilla Firefox','uninstall','helper.exe')
parametre = '/SetAsDefaultAppGlobal'
commandsm = ' '.join([commande,parametre])
run(commandsm)
Why can't I just do it?
Code: Select all
run(r'C:\Program Files (x86)\Mozilla Firefox\uninstall\helper.exe /SetAsDefaultAppGlobal')
?

Has anyone succeeded?
The code
Code: Select all
commande = makepath(programfiles,'Mozilla Firefox','uninstall','helper.exe')
parametre = '/SetAsDefaultAppGlobal'
commandsm = ' '.join([commande,parametre])
run(commandsm)
makes me:
CalledProcessErrorOutput: Command 'C:\\Program Files\\Mozilla Firefox\\uninstall\\helper.exe /SetAsDefaultAppGlobal' returned non-zero exit status 1.
Output: 'C:\Program' is not recognized as an internal
or external command, operable program or batch file.
and a simple run
Code: Select all
run_notfatal(r'"C:\Program Files\Mozilla Firefox\uninstall\helper.exe" /SetAsDefaultAppGlobal')
yields:
FATAL ERROR: CalledProcessErrorOutput: Command '"C:\\Program Files\\Mozilla Firefox\\uninstall\\helper.exe" /SetAsDefaultAppGlobal' returned non-zero exit status 2.
Output:
Exit code: 3

Good morning,
While reading:
http://kb.mozillazine.org/Default_browser#Windows
Code: Select all
firefox.exe -silent -setDefaultBrowser
Seems more appropriate. Launch it in the session_setup() section of the Firefox package and it should work for all users.
For those interested, Firefox 60 is coming this summer with a set of GPO templates that can be integrated into AD (ADMX files):

Sorry to be a pain, but the following code:
Code: Select all
run(r'"C:\Program Files\Mozilla Firefox\firefox.exe" -silent -setDefaultBrowser"')
yields:
FATAL ERROR: CalledProcessErrorOutput: Command '"C:\\Program Files\\Mozilla Firefox\\firefox.exe" -silent -setDefaultBrowser"' returned non-zero exit status 1.
I'm moving the quotation marks and apostrophes around, but nothing is working...

The last quotation mark is unnecessary

Ah yes, indeed, but even after correcting it I still have an error...
Code: Select all
run(r'"C:\Program Files\Mozilla Firefox\firefox.exe" -silent -setDefaultBrowser')

Good morning,
Would it be possible to install Firefox 32 on the posts?
The call path would then be
C:\Program Files (x86\Mozilla Firefox\
I wasn't up to date on the new procedure for setting the default browser in Windows 10:
I haven't found any other functional "scriptable" methods under Windows 10 for Firefox, except by using a third-party executable:
https://github.com/sampalmer/set-default-browser
Worth testing, but it's preferable to use a GPO.

Until yesterday, I was installing a 32-bit Firefox package everywhere, but the latest "lesfourmisduweb" packages uninstalled this 32-bit version and installed the 64-bit one. A folder called "C:\Program Files (x86)\Mozilla Firefox" remains on the computers, but it's almost empty.
And there's no longer a default browser on the computers, so users can no longer open website shortcuts on their desktops...
