Network request details

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 five different pages:

  • Headers
  • Cookies
  • Params
  • Response
  • Timings

From Firefox 30 onwards, there's a sixth page that appears only if the content type is HTML, the Preview page.

Clicking the icon to the left of the tabs closes the pane and returns you to the list view.

This tab lists basic information about the request including URL and status code, as well as the HTTP request and response headers that were sent:

You can filter the headers that are displayed:


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.


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


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:


This feature is new in Firefox 30.

From Firefox 30 onwards, if the file type is HTML a sixth tab appears labeled "Preview". This renders just that HTML:

Performance analysis

The performance analysis tool is new in Firefox 29.

From Firefox 29 onwards, 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 at the bottom of the Network Monitor:

(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 thing is my job isn't that hard

by BeerWhore

After training I've been hitting my numbers like I've worked there for years. I don't have performance nor attitude issues at work.
Monitoring behavior at home would be an issue but I'm actually pretty chill to live with (so I've been told). I'm clean, I make nice food and share it, I'm actually pretty quiet.
There is the factor of my occasional wine/beer binge that I'd need to watch but that's not a bad thing.
Yeah, there are folks at work that would be assholes. And I'd worry that she'd try to "make an example" of me by making things harder on me just to show that I'm not influencing her

Sure. yeah, that's it.

Better Interviews Said Key to Exit Polls By WILL LESTER, Associated Press Writer
Sat May 14, 6:39 PM ET
MIAMI BEACH, Fla. - Better training of interviewers to get a proper sample of voters after they cast ballots will be key to improving the performance of exit polls, one pollster who handled the 2004 election surveys said Saturday.
Exit polls on Election Day 2004 overstated support for Democrat John Kerry overall and in many key states, which led to widespread confusion that day about the election eventually won by President Bush.
The exit polls contacted more supporters of Kerry than of Bush because of "the failure of interviewers to follow the selection rate," said Warren Mitofsky, who conducted the exit polls along with Joe Lenski of Edison Media Research USB 3.0 to DVI / VGA External Video Card Multi Monitor Adapter - 2048x1152 - USB 3.0 Graphics Adapter M/F

Look beyond APM to unified performance monitoring  — TechTarget
ORLANDO, Fla. -- The lack of interoperability among traditional performance monitoring tools means data centers must use -- and pay for -- multiple tools. But movement toward unified performance monitoring could change all that.
