Network monitor toolbar
=======================
The network monitor provides two toolbar areas, one above the main section, and another below.
Toolbar
*******
The toolbar is at the top of the main network monitor window. (Prior to Firefox 77, this toolbar was arranged somewhat differently.)

It provides:
- An icon to clear the :doc:`network request list <../request_list/index>`
- A box enabling you to :ref:`filter requests <request-list-filtering-requests>` by URL and by properties.
- A set of tool icons:
- Pause (or **resume**) recording network log
- **Search** the log
- **Request Blocking**
- An array of buttons to filter the network request list by type:
- by the content type of the response
- XHR requests
- WebSocket upgrades and messages (labeled **WS**)
- Other requests
- A checkbox that allows you to disable caching.
- **Throttling** menu, to simulate various connection types
- A menu of other actions:
- **Persist Logs**: By default, the Network Monitor is cleared each time you navigate to a new page or reload the current page. When you select **Persist Logs**, the log is not cleared on page load.
- **Import HAR** imports a HAR (HTTP Archive) file.
- **Save All as HAR** opens a file dialog box so you can save the current contents of the Network log as a HAR file with the extension ```.har```.
- **Copy All as HAR** copies the current contents of the Network log to the clipboard in HAR format.
A second toolbar area at the bottom of the network monitor provides:

- An icon to launch :doc:`performance analysis <../performance_analysis/index>`.
- A summary of this page, including the number of requests, total size, and total time.
