Trying to figure out how to install Firefox on XP systems that will have mulitple user accounts. For several months I've been using Simon's script to install Firefox with all my favorite extensions. The limitation is that the extensions only work for the user under which the install was run. If I log on as a different user the extensions are in the list (Tools - Extensions) but I can't do anything with them.

Tonight I found Silence of the Foxes method and that works pretty good. I've read the entire thread. This method works for multiple users for me by running the created installer as each user. This would be OK, but I'd really like to do this just one time. I would have settled for this but am having problems with Forecastfox (that I'll start a separate thread for).

I know it has to do with profiles and maybe setting a default profile of some sort. Please don't tell me to search. I've spent hours doing that but still haven't been able to figure it out.

Could someone please help, this is driving me nuts.

First install Firefox, but dont start it up right away. Launch Firefox using the Default Profile using the following shortcut:
%programfiles%\Mozilla Firefox\firefox.exe" -profile defaults\profile

Once your done getting Firefox as you like it, create a Self Extracting Archive of the default profile folder.

1) Install Firefox or Thunderbird silently using the -ms switch.
2) Create/Run Profle.cmd to delete the default profile mozilla creates.

3) Run Profile.exe (WinRAR SFX) to extract you custom default profile.

Now for every user that starts up firefox they will have a copy of the default profile!

<Edit> Looks like i was beeten to it, I would say DigeratiPrime's way is probly easier (with the SFX)</Edit>

look at usung the "-profile" switch (do a search for portable firefox to see its context as I'm only familiar with the concept) which you can then create a folder "C:\ffprof\" and have the -profile switch point to that to (and put all the links in the all users profile, not an individual's) and anytime you run it from those shortcuts it will run with that profile, this isn't an elegant solution, but your other option would be to use GUIrunonce (so it runs the first time a user logs in) and run a batch that copies the profile from the admin profile to their "%AppData%\Mozilla\Firefox\" folder.
