This will open the Nanny window. It's a blue button in the top-right corner of the Nanny window. Doing so will install the Nanny extension. It resembles a clock in the top-right corner of the Chrome window. Right-clicking this icon prompts a drop-down menu.  If your computer doesn't have a right mouse button, use two fingers to tap the trackpad instead of right-clicking. On a Mac, you can press Control and click the icon instead. This option is near the top of the drop-down menu. Doing so opens the Nanny page. You'll find it in the top-left side of the page. Type a name into the "Block Set Name" field at the top of the page. Since you're only blocking Facebook, consider naming this set "Social Media" or "Facebook Only". Type https://www.facebook.com/ into the "URLs" field. Type the start and stop time for the block into the "Block Time" text field in military time. For example, to block from 11:00 AM to 5:00 PM and 9:00 PM to 8:00 AM, you would type 1100-1700,2100-0800. In the "Apply On Days" row, make sure there is a checkmark next to each day of the week for which you want to block Facebook. It's in the bottom-left corner of the page. Doing so will save your settings and block Facebook during your selected time frame.
