- Open the file (by double-click the file with your mouse) to start the Firefox install wizard.
- If you are running Windows Vista, you may get a User Account Control prompt. In this case, allow the setup to run by clicking Continue.
A welcome screen appears.
- Click Next to continue. The Setup Type screen appears. A "Standard" setup is selected by default (using the custom option is only recommended for experienced users).
- Firefox installs itself as your default browser. If you do not want Firefox to be your default browser, clear the check box Use Firefox as my default web browser.
- Click Next.
- Once Firefox has been installed, click Finish to close the setup wizard.
