"You might try installing FF and then denying access on the installation ""extensions"" directory for creating a new file to the group ""Everyone"".

For the registry installed extensions, you should be able to deny access to the registry path/key. This is easily done with regedit - locate the registry entity you want to change and use the context menu to change permissions on it. Be very careful; changing the registry in the wrong way can prevent your system from booting. Make careful note of what you do and have a recovery disk with regedit handy just in case."
