-<p>مانیتور شبکه همه درخواست های شبکه فایرفاکس را نشان می دهد (به عنوان مثال، هنگامی که یک صفحه را بارگذاری می کند یا به دلیل XMLHttpRequests)، چه مدت هر درخواست طول می کشد و جزئیات هر درخواست.</p>
-
-<h2 id="باز_کردن_مانیتور_شبکه">باز کردن مانیتور شبکه</h2>
-
-<p>چند راه مختلف برای باز کردن مانیتور شبکه وجود دارد:</p>
-
-<div class="geckoVersionNote">
-<p>میانبر صفحه کلید در فایرفاکس 55 تغییر کرده است</p>
-</div>
-
-<ul>
- <li>فشاردهید  <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>E</kbd> ( <kbd>Command</kbd> + <kbd>Option</kbd> + <kbd>E</kbd> در سیستم عامل مک).</li>
- <li>"شبکه" را از منوی Web Developer انتخاب کنید (که منوی زیر در منوی Tools در OS X و لینوکس است).</li>
- <li>روی نماد آچار کلیک کنید (<img alt="" src="https://mdn.mozillademos.org/files/12710/wrench-icon.png" style="height: 21px; width: 21px;">), که در نوار ابزار اصلی یا زیرمنو روبرواست (<img alt="" src="https://mdn.mozillademos.org/files/12712/hamburger.png" style="height: 20px; width: 22px;">),سپس انتخاب "شبکه".</li>
-</ul>
-
-<p>مانیتور شبکه در پایین پنجره مرورگر ظاهر می شود. برای دیدن درخواست ها، صفحه را بارگیری کنید:</p>

-<p><img alt="" src="https://mdn.mozillademos.org/files/13535/1-new-overview-small.png" style="display: block; height: 831px; margin: 0px auto; width: 1100px;"></p>
-
-<p>مانیتور شبکه هر زمان که جعبه ابزار باز است، حتی اگر شبکه مانیتور خود انتخاب نشده باشد، درخواست های شبکه را ثبت می کند. این بدان معنی است که شما می توانید یک صفحه را در اشکال زدایی، به عنوان مثال، کنسول وب، شروع کنید، سپس به Network Monitor بروید تا فعالیت شبکه را بدون نیاز به بارگذاری مجدد صفحه ببینید.</p>
-
-<h2 id="نمای_کلی_UI">نمای کلی UI</h2>
-
-<p>UI به چهار قسمت اصلی تقسیم می شود:</p>
-
-<ul>
- <li>صفحه اصلی حاوی نوار ابزار، لیست درخواست شبکه و پنجره جزئیات اطلاعات درخواست شبکه است:</li>

-
-<h2 id="نوار_ابزار">نوار ابزار</h2>
-
-<p>از فایرفاکس 47 به بعد، نوار ابزار در بالای پنجره اصلی قرار دارد. در نسخه های قبلی فایرفاکس، در پایین آن است.</p>

-<h2 id="Network_request_list">Network request list</h2>
-
-<p>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:</p>

-
-<h4 id="Cause_column">Cause column</h4>
-
-<p>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:</p>
-
-<ul>
- <li>document: The source HTML document.</li>
- <li>img: {{htmlelement("img")}} element.</li>
- <li>imageset: {{htmlelement("img")}} element.</li>
- <li>script: A JavaScript file.</li>
- <li>stylesheet: A CSS file.</li>
-</ul>
-
-<div>
-<p>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.</p>
-
-<p><img alt="" src="https://mdn.mozillademos.org/files/13575/stack-trace-new-small.png" style="display: block; margin: 0 auto;"></p>
-
-<p>You can then click on any of the entries in the popup to open up the relevant script in the <a href="/en-US/docs/Tools/Debugger">Debugger</a> pane.</p>
-</div>
-
-<h3 id="Timeline">Timeline</h3>
-
-<p>The request list also displays a timeline for the different parts of each request.</p>
-
-<p><img alt="" src="https://mdn.mozillademos.org/files/13543/8-new-timeline-small.png" style="display: block; height: 239px; margin: 0px auto; width: 900px;"></p>
-
-<p>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 <a href="/en-US/docs/Tools/Network_Monitor#Timings">Timings</a> page.</p>
-
-<p>Starting in Firefox 45, the timeline also contains two vertical lines:</p>
-
-<ul>
- <li>the <span style="color: blue;">blue</span> line marks the point at which the page's <code><a href="/en-US/docs/Web/Events/DOMContentLoaded">DOMContentLoaded</a></code> event is triggered</li>
- <li>the <span style="color: red;">red</span> line marks the point at which the page's <code><a href="/en-US/docs/Web/Events/load">load</a></code> event is triggered</li>

-<h3 id="Filtering_requests">Filtering requests</h3>
-
-<p>You can filter requests by content type, by whether they are XMLHttpRequests or WebSocket requests, by URL, or by request properties.</p>
-
-<h4 id="Filtering_by_content_type">Filtering by content type</h4>
-
-<p>To filter by content type, use the buttons in the <a href="/en-US/docs/Tools/Network_Monitor#Toolbar">toolbar</a>.</p>
-
-<h4 id="Filtering_XHR">Filtering XHR</h4>
-
-<p>To see only {{Glossary("XHR (XMLHttpRequest)", "XHR")}} requests, use the "XHR" button in the <a href="/en-US/docs/Tools/Network_Monitor#Toolbar">toolbar</a>.</p>
-
-<h4 id="Filtering_WebSockets">Filtering WebSockets</h4>
-
-<div class="geckoVersionNote">
-<p>New in Firefox 48</p>
-</div>
-
-<p>To see only WebSocket connections, use the "WS" button in the <a href="/en-US/docs/Tools/Network_Monitor#Toolbar">toolbar</a>.</p>
-
-<p>To monitor the data exchanged in WebSocket connections, try the <a href="https://addons.mozilla.org/en-US/firefox/addon/websocket-monitor/">WebSocket Monitor add-on</a>.</p>
-
-<h4 id="Filtering_by_URL">Filtering by URL</h4>
-
-<p>To filter by URL, use the search box in the <a href="/en-US/docs/Tools/Network_Monitor#Toolbar">toolbar</a>. Click in the search box, or press <kbd>Ctrl</kbd> + <kbd>F</kbd> (or <kbd>Cmd</kbd> + <kbd>F</kbd> 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.</p>
-
-<p>From Firefox 45,  you can filter requests that <em>don't</em> 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.</p>
-
-<h4 id="Filtering_by_properties">Filtering by properties</h4>
-
-<div class="geckoVersionNote">
-<p>New in Firefox 55</p>
-</div>
-
-<p>To filter by specific request properties, use the search box in the <a href="/en-US/docs/Tools/Network_Monitor#Toolbar">toolbar</a>. 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 (<code>-</code>) negates the filter. You can combine different filters together by seperating them with a space.</p>

-<h2 id="Pausing_and_resume_network_traffic_recording">Pausing and resume network traffic recording</h2>
-
-<p>In Firefox 58+, 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.</p>
-
-<p>The button can be found at the far left of the main Network Monitor toolbar, and looks like a typical pause button — <img alt="" src="https://mdn.mozillademos.org/files/15625/pause-icon.png" style="height: 23px; width: 34px;">.</p>
-
-<p>you can see it here in context:</p>

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

-<p>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.<br>
- <br>
- To run the performance analysis tool click the stopwatch icon in the <a href="/en-US/docs/Tools/Network_Monitor#Toolbar">toolbar</a>.</p>
-
-<p>(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.)</p>
-
-<p>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:</p>

-
-<p>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.</p>
-
-<p>To get back to the Network Monitor's list of network requests click the "Back" button on the left.</p>
-
-<p>Clicking on a slice of the pie takes you to the Network Monitor for that run, with a filter automatically applied to see <a href="/en-US/docs/Tools/Network_Monitor#Filtering_by_content_type">only that resource type</a>.</p>
