I can't install Firefox without letting it alter my system. I can install all other browsers as an unprivileged user, but not Firefox.

Using you file browser, right click the installer and select Run As Administrator.

Obviously, this is what I DO NOT WANT. I want to install Firefox as UNPRIVILEGED user. Which means without administrator rights. Is it clear?

If you have write access to "C:\Program Files (x86)\Mozilla Firefox\" as an unprivileged user then you should be able to install Firefox, but you can't install the Mozilla Maintenance Service to update in the background.

Did you try your solution? As soon as I cancel UAC prompt, installation aborts. I can't start installation without it showing UAC prompt. Thus I can't choose path to install browser. You know, all other browsers allow to choose installation type between "All users" and "Current user". While "All users" type requires admin rights and UAC prompt appears if user chooses it, "Current user" does not require admin rights, so no UAC prompt appears if user chooses this type. With Firefox I am not given the choice. It requires admin rights as soon as installation is launched. It even ignores set __COMPAT_LAYER=RunAsInvoker environment variable.
