I'm sorry that it seems to be difficult to get going. The add-on page has screenshots showing how to add sites, and links to a homepage (which also includes an FAQ) and support email under "More Information". Is there something you would recommend including on the add-on's page?

If you're trying to get to the Options page and change things there, here's how to do that:

1. In the Firefox menu, go to Tools -> Add-ons. (Or click Ctrl+Shift+A).
2. Ensure you are in the Extensions submenu (the Extensions and puzzle piece icon on the left side of the screen should be blue); if you are not, click Extensions.
3. Find Morning Coffee Quantum in your list of extensions, and click the Options button to the right of its description.
4. Make your desired changes. Make sure to click the Save button at the bottom afterwards!

I hope this helps. If you need more information about something, don't hesitate to ask.
