Ask your sister to install things for you.
It sounds like there is a reason you don't have admin access.......
You are asked for the password to the Administrator account.
You do not need a password to install Mozilla Firefox unless you are on a non-admin or unprivileged user account. In this case, the password is whatever the password to the Administrator account is.
Install firewall and antivirus, also set a password up for your account. Disable Guest account. Install password for Administrator account. Dont' use internet explorer, MSN. Use something different with higher security.

Individuals can have their own accounts on a Mac. These can be set up in the Accounts section of System Preferences. The account can be classed as Standard or Administrator. Administrator accounts allow access to parts of the system denied to standard account - such as the ability to install software. The settings for the Administrator account will have a name and a password that the user can set to anything they wish.
Yes. The administrator can turn the parental controlled account into an administrator account. Then the administrator can go into the account and install something into the account. Then the administrator can go back into the administrators account and turn the account back into a parental controlled account.
On Windows 7 you must have at least one administrator account at all times. If your main account is a standard account, that's fine, but you must also keep an administrator account. In fact, it is recommended that people use a standard account for everyday use and only use an administrator account when needed (for example if you're going to install or uninstall any programs). You canNOT install/uninstall programs with a standard account, and there are lots of other things that you cannot do with a standard account, which is why at least one administrator account is needed. Just use a password that you can remember for the administrator and don't give it to anyone.
If you are on a network, you may need an administrator password to install software of any kind. But if you are upgrading your home computer, you won't need any password.
Administrator
To put it simply: You Can't. In Windows Vista, you must be a member of the local Administrators group (or have Admin credentials) to enable/disable User Account Control. You can install Smart UAC Replacement which will switch it off. But first answerer was right to install it you will need to know password/login of Administrator.
Sometimes programs only install on the administrator account.
You get to pick, it will not automatically install them. Administrator is set up in safe mode, if your counting that account.
