The Network Monitor shows you all the network requests Firefox makes (for example, when it loads a page, or due to XMLHttpRequests), how long each request takes, and details of each request.
Opening the Network Monitor
There are a few different ways to open the Network Monitor:

- Select "Network" from the Web Developer menu, (which is a submenu of the Tools menu on OS X and Linux).
- Click the wrench icon (), which is in the main toolbar or under the Hamburger menu (), then select "Network".

- The performance analysis view is a separate screen:
