1. From your firefox browser, select the hamburger menu in the upper right corner.
2. Select "Settings."
3. Select "Privacy and Security."
4. Scroll down to the "Permissions" section.
5. Next to the "Block pop-up windows" select "Exceptions..."
6. In the "Address of website" field, type in: https://www.drfirst.com/.
7. Select "Allow", then select "Save Changes."

You should now be able to open DrFirst. You can test this by selecting the "ePrescribe" button on a client's chart.
