Firestocks od sbellone

This Firefox extension adds a button to your Firefox toolbar. When you click on it, it opens a simple popup displaying the latest info about the stocks you follow.

It uses the Financial Modeling Prep API and requires the creation of an API Key at https://site.financialmodelingprep.com/developer

The followed stocks can be set in the extension's options page.

Data is refreshed each time you open the popup.
