Mozilla Firefox – how to prevent the first run Firefox Import Settings and Data Wizard and the first run welcome page

September 23rd, 2009 Leave a comment Go to comments

In my work I look after software installation for a number of computer labs and one of the applications that I deploy is Mozilla Firefox. Some time ago I discovered the excellent FrontMotion Firefox Community Edition which is exactly the same as the Mozilla version except that it allows for the possibility of configuring many of the browser settings through Active Directory Group Policy.

If you haven’t seen FrontMotion Firefox before check it out here: http://www.frontmotion.com/FMFirefoxCE/index.htm

The associated ADM templates are available on this page and as you can see they don’t hang about in getting the latest versions packaged up ready for you to use: http://www.frontmotion.com/FMFirefoxCE/download_fmfirefoxce.htm

    Disabling the first run Import Settings and Data Wizard:

Once deployed; one thing was bugging me. Whenever a user launches Firefox for the first time (and they do not have an existing Firefox profile they get the Import Wizard to Import Settings and Data… and once they’ve made it past that instead of the default homepage (which I set to our organisation’s web site) they get the Welcome to Version X.x firstrun tab.

Luckily there is a way to disable the Firefox Import Bookmarks and Settings Wizard that runs on first launch and if users do want to import their IE Favorites they can still do this once Firefox has launched from the main menu: File > Import

To disable the first run Import Wizard simply create a file named override.ini containing this text:

[XRE]
EnableProfileMigrator=false

Copy it into: C:\Program Files\Mozilla Firefox\
You could do this using a command script that runs on startup.

The bug is documented here: https://bugzilla.mozilla.org/show_bug.cgi?id=286557

    Disabling the first run Welcome to Version X.x tab:

But wait! We don’t want that annoying Welcome to Version X.x page to appear either when the user launches Firefox for the first time. We just want our home page to appear.

So using the Mozilla ADM template that works with FrontMotion Firefox Community Edition you can disable this via group policy:

In the ADM under locked settings simply set:
browser.startup.homepage_override.mstone to ignore

This bug is documented here: https://bugzilla.mozilla.org/show_bug.cgi?id=102313

Eh voila, user logs onto PC for the first time and starts Firefox, up comes the homepage!

    Perfect. Exactly what I am looking for.
    Thank you!

    It is exactly what I am looking for as well, but unfortunately it does not appear to
    work with Firefox 25.0 anymore.
    (I mean the trick with override.ini to stop the profile migrator)
    Is there a new method to do this?

    Rob,

    The new location for the override.ini is ‘C:\Program Files\Mozilla Firefox\browser’. Also, if you are using mozilla.cfg to lock preferences and it’s not being applied you may wish to use Notepad ++. I notice the Mozilla COnfigurator is not working at the moment so I opened a default mozilla.cfg in Notepad ++ and theres a few subtle changes.
