O Monitor de Rede mostra-lhe os pedidos de rede que o Firefox efetua (por exemplo, quand o este carrega uma página, ou ddevido a XMLHttpRequests), quanto tempo demora cada pedido, e detalhes de cada pedido.

- -

Abrir o Monitor de Rede

- -

Existem algumas maneiras diferentes de abrir o 'Monitor de Rede':

- -
-

Por favor, note que o atalho de teclado foi alterado na versão 55 do Firefox

-
- - - -

The Network Monitor will appear at the bottom of the browser window. Reload the page to see the requests:

- -

- -

The Network Monitor records network requests any time the Toolbox is open, even if the Network Monitor itself is not selected. This means you can start debugging a page in, for example, the Web Console, then switch to the Network Monitor to see network activity without having to reload the page.

- -

IU - Sinopse

- -

A IU é dividida em 4 partes principais:

- - - -

- - - -

- -

Barra de Ferramentas

- -

From Firefox 47 onwards, the toolbar is at the top of the main window. In earlier versions of Firefox, it's at the bottom.

- -

It provides:

- - - -
-

Note: From Firefox 58 onwards, the "Flash" filter button is no longer available, and Flash requests are included in the "Others" filter ({{bug(1413540)}}).

-
- -

Lista de pedidos de rede

- -

By default, the Network Monitor shows a list of all the network requests made in the course of loading the page. Each request is displayed in its own row:

- -

By default, the Network Monitor is cleared each time you navigate to a new page or reload the current page. You can override this behavior by checking "Enable persistent logs" in the Settings.

- -

Colunas de pedido de rede

- -

From Firefox 55 onwards, you can toggle different columns by right-clicking on the table header and choosing the specific column from the context menu. A "Reset Columns" option is also available to reset the columns to their initial configuration. Here is a list of all available columns:

- - - -

The toolbar at the top labels these columns, and clicking the label sorts all the requests by that column.

- -

Miniaturas de imagem

- -

If the file is an image, the row includes a thumbnail of the image, and hovering over the filename shows a preview in a tooltip:

- -

- -

Ícones de segurança

- -

The Network Monitor displays an icon in the Domain column:

- -

- -

This gives you extra information about the security status of the request:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
ÍconeSignificado
HTTPS
Weak HTTPS (for example, a weak cipher was used)
Failed HTTPS (for example, a certificate was invalid)
HTTP
Localhost
- -

For weak and failed HTTPS requests, you'll see more details of the problem in the Security tab.

- -

Cause column

- -

The Cause column indicates what the cause of the request was. This is usually fairly obvious, and you can generally see the correlation between this and the Type column entry. The most common values are:

- - - -
-

When a request was triggered by JavaScript, a small JS icon is shown to the left of the entry in the Cause column. Hovering over this displays a popup containing the stack trace for the request, to provide more clues as to why a request happened. Note that since Firefox 55, stack traces can be found in the Stack Trace tab of the {{anch("Network request details")}} panel instead.

- -

- -

You can then click on any of the entries in the popup to open up the relevant script in the Debugger pane.

-
- -

Barra Cronológica

- -

The request list also displays a timeline for the different parts of each request.

- -

- -

Each timeline is given a horizontal position in its row relative to the other network requests, so you can see the total time taken to load the page. For more details on the color-coding used here, see the section on the Timings page.

- -

Starting in Firefox 45, the timeline also contains two vertical lines:

- - - -

Pedidos de filtragem

- -

You can filter requests by content type, by whether they are XMLHttpRequests or WebSocket requests, by URL, or by request properties.

- -

Filtering by content type

- -

To filter by content type, use the buttons in the toolbar.

- -

Filtering XHR

- -

To see only {{Glossary("XHR (XMLHttpRequest)", "XHR")}} requests, use the "XHR" button in the toolbar.

- -

Filtering WebSockets

- -
-

Novo na versão 48 do Firefox

-
- -

To see only WebSocket connections, use the "WS" button in the toolbar.

- -

To monitor the data exchanged in WebSocket connections, try the WebSocket Monitor add-on.

- -

Filtering by URL

- -

To filter by URL, use the search box in the toolbar. Click in the search box, or press Ctrl + F (or Cmd + F on a Mac), and start typing. The list of network requests will be filtered to include only requests that contain your filter string, in either the Domain or the File portions.

- -

From Firefox 45,  you can filter requests that don't contain your filter string by prefixing your query with the "-" operator. For example, the query "-google.com" will show all requests that don't have "google.com" in their URL.

- -

Filtering by properties

- -
-

Novo na versão 55 do in Firefox

-
- -

To filter by specific request properties, use the search box in the toolbar. The search box recognizes specific keywords, which can be used to filter the requests by specific request properties. Those keywords are followed by a colon and a related filter value. The filter values are matched case insensitive. Prepending a minus (-) negates the filter. You can combine different filters together by seperating them with a space.

- - - -

Context-clicking on a row in the list displays a context menu with the following options:

- - - -

Edit and Resend

- -

This option opens an editor enabling you to edit the request's method, URL, parameters, and headers, and resend the request.

- -

Open in New Tab

- -

Resends the request in a new tab — very useful for debugging asynchronous requests.

- -
-

Nota: Since Firefox 59, POST requests are correctly resent as POST requests ({{bug(1220758)}}), with the expected POST parameters ({{bug(1407515)}}).

-
- -

Copy as cURL

- -

This option copies the network request to the clipboard as a cURL command, so you can execute it from a command line. The command may include the following options:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
-X [METHOD]If the method is not GET or POST
--dataFor URL encoded request parameters
--data-binaryFor multipart request parameters
--http/VERSIONIf the HTTP version is not 1.1
-IIf the method is HEAD
-H -

One for each request header.

- -

From Firefox 34, if the "Accept-Encoding" header is present, the cURL command will include --compressed instead of -H "Accept-Encoding: gzip, deflate". This means that the response will be automatically decompressed.

-
- -

Copy/Save All As HAR

- -

These options create an HTTP Archive (HAR) for all requests listed. The HAR format enables you to export detailed information about network requests. 'Copy All As HAR' copies the data to the clipboard, 'Save All As HAR' opens a dialog allowing you to save the archive to disk.

- -

Note that as of Firefox 61, we have included a toolbar menu to make these options easier to discover ({{bug(1403530)}}). The new 'HAR' dropdown menu includes both the 'Copy All As HAR' and 'Save All As HAR' commands, as well as an 'Import...' option.

- -

- -

Detalhes do pedido de rede

- -

Clicking on a row displays a new pane in the right-hand side of the network monitor, which provides more detailed information about the request.

- -

- -

The tabs at the top of this pane enable you to switch between the following pages:

- - - -

Clicking the icon at the right-hand end of the toolbar closes the details pane and returns you to the list view.

- -

Cabeçalhos

- -

This tab lists basic information about the request:

- -

- -

This includes:

- - - -

You can filter the headers that are displayed:

- -

- -
-

New in Firefox 54

-
- -

From Firefox 54 onwards, you will see a question mark icon next to each header in the Status code row — this is a link to more information about that particular status code, in the MDN documentation of the HTTP headers.

- -

Cookies

- -

This tab lists full details of any cookies sent with the request or response:

- -

- -

As with headers, you can filter the list of cookies displayed. The full list of cookie attributes is shown — see the below screenshot from a Response cookies examples with further attributes shown.

- -

cookies panel in firefox devtools network monitor, showing a number of cookie attributes including samesite

- -

The samesite attribute has been shown since Firefox 62 ({{bug("1452715")}}).

- -

Paramêtros

- -

This tab displays the GET parameters and POST data of a request:

- -

- -

Resposta

- -

The complete content of the response. If the response is HTML, JS, or CSS, it will be shown as text:

- -

- -

If the response is JSON, it will be shown as an inspectable object.

- -

If the response is an image, the tab displays a preview:

- -

- -

Cache

- -

If the response is cached (i.e. a 304), the Cache tab will display details about that cached resource.

- -

- -

These details include:

- - - -

HTML preview

- -

From Firefox 59 onwards, if the response is HTML, a preview of the rendered HTML appears inside the Response tab, above the response payload.

- -

- -

Timings

- -

The Timings tab breaks a network request down into the following subset of the stages defined in the HTTP Archive specification:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
NomeDescrição
Blocked -

Time spent in a queue waiting for a network connection.

- -

The browser imposes a limit on the number of simultaneous connections that can be made to a single server. In Firefox this defaults to 6, but can be changed using the network.http.max-persistent-connections-per-server preference. If all connections are in use, the browser can't download more resources until a connection is released.

-
DNS resolutionTime taken to resolve a host name.
ConnectingTime taken to create a TCP connection.
SendingTime taken to send the HTTP request to the server.
WaitingWaiting for a response from the server.
ReceivingTime taken to read the entire response from the server (or cache).
- -

It presents a more detailed, annotated, view of the timeline bar for that request showing how the total wait time is split into the various stages:

- -

- -

Segurança

- -

If the site is being served over HTTPS, you get an extra tab labeled "Security". This contains details about the secure connection used including the protocol, the cipher suite, and certificate details:

- -

- -

The Security tab shows a warning for security weaknesses. Currently it warns you about two weaknesses:

- -
    -
  1. Using SSLv3 instead of TLS
    2. -
  2. Using the RC4 cipher
    3. -
- -

- -

Stack trace

- -

Since Firefox 55, stack traces are shown in the Stack Trace tab, for responses that have a stack trace of course.

- -

- -

Pausing and resume network traffic recording

- -

In Firefox 58 and above, the Network Monitor has a button that pauses and resumes recording of the current page's network traffic. This is useful in situations where, for example, you are trying to get a stable view of a page for debugging purposes, but under normal circumstances the view keeps evolving due to persistent network requests. The pause button allows you to look at a certain snapshot.

- -

The button can be found at the far left of the main Network Monitor toolbar, and looks like a typical pause button — .

- -

You can see it here in context:

- -

- -

Once pressed, the button changes to a play icon, and you can toggle network traffic recording back on by pressing it again.

- -

Análise de desempenho

- -

The Network Monitor includes a performance analysis tool, to help show you how long the browser takes to download the different parts of your site.
-
- To run the performance analysis tool click the stopwatch icon in the toolbar.

- -

(Alternatively, if you have only just opened the Network Monitor, so it's not yet populated with the list of requests, you'll get a stopwatch icon in the main window.)

- -

The Network Monitor then loads the site twice: once with an empty browser cache, and once with a primed browser cache. This simulates the first time a user visits your site, and subsequent visits. It displays the results for each run side by side, or vertically if the browser window is narrow:

- -

- -

The results for each run are summarised in a table and a pie chart. The tables group resources by type, and show the total size of each resource and the total time it took to load them. The accompanying pie chart shows the relative size of each resource type.

- -

To get back to the Network Monitor's list of network requests click the "Back" button on the left.

- -

Clicking on a slice of the pie takes you to the Network Monitor for that run, with a filter automatically applied to see only that resource type.

- -

Throttling

- -

In Firefox 61 onwards, the toolbar includes a Throttling dropdown, which allows you to throttle your network speed to emulate various different network speed conditions. Simply choose an option from the menu, and it will persist across reloads.

- -

- -

The characteristics emulated are:

- - - -

The table below lists the numbers associated with each network type, but please do not rely on this feature for exact performance measurements; it's intended to give an approximate idea of the user experience in different conditions.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
