# Can FireFox be Installed with a Fixed Set of Extensions that cannot be Changed by End-Users?

There is a way to bundle FireFox with a fixed list of extensions and that users won't be able to install/uninstall them after ? A big company with lots of IE6 search a way to do that, they'are afraid about extensions and security if users can install anything.

It is also possible to customize the installer to change the default user profile, and to lock machine-wide settings. Basically anything which can be configured in about:config can be configured that way. Google around for "customized firefox install". I can post some links later if you have trouble with it.
