    UPDATE:
    The export as HAR is built-in since Firefox 41, you do not need to install Firebug and the NetExport extension.
    Just show the network profiler toolbar through Menu > Developer > Network. Then reload the page. Right-click anywhere in the table and select the entry called Save all as HAR, select the destination file. You are done.

    Firefox users need to take some additional action prior to capturing a HAR:

    •Install the Firefox extension Firebug.
    •Install the Firebug extension NetExport. ...
    •Open the Firebug console using one of these methods: ...
    •Navigate to the Net tab in Firebug console.
    •Refresh the page to start capturing the traffic between the browser to the server.

    While we recommend Chrome for this sometimes internal policy dictates the use of particular browsers. We will continue to try and update documentation to reflect all supported browsers.

    @James - I believe by default it will save to your "Downloads" folder, but you can set your downloads location in your Chrome settings (Chrome > Preferences > Advanced Settings > Downloads.)

    When generating my HAR file as instructed, the file size is 37.8 mb which exceeds the 20 mb limit imposed by ZD. How should we upload these larger files for review?

    Hi Darryl,

    You can compress HAR files.  When I tried to compress a 22.4MB HAR file the zip file became 13.2MB.

    For Google Chrome, you must press the download icon in the settings menu bar to download the .har file

    Hello, Can you provide screenshots from a PC and not just a MAC OS?

    Hey Joshua,

    The instructions should be fairly similar and will differ based on the browser you're using. I was able to track down an external article that goes over capturing a HAR file using different browsers that may also help: How to Generate Network Captures for Troubleshooting

    Is there a particular step you're getting stuck on while using Windows?

    Let me know!

    It's less my trouble and more when I try and show the article to people who are less tech-savvy when directing them to do these instructions since they are geared for a Mac Os and some of the steps while analogous to what I would do on a PC, it would definitely lend some clarity to those users who are not on a Mac. Just to cite some sources: According to the latest numbers from NetMarketShare, the Mac now accounts for 9.57 percent of all PCs currently in use. Windows is of course still number one, with 88.77 percent of all usage. Seems it would be nice to have a run-through on Chrome on a PC with the different locations and names and clicks they would need to do. From a ZDNet article: By the United States' government's count, Chrome is the most popular web browser followed by Internet Explorer and then Safari. 

    I feel this makes a good case to maybe have a run-through on a PC with Chrome if you are wanting to reach beyond a <10% used OS. I use a Mac at home and a PC at work, so I am familiar with both, but this is more about getting the best reach for the largest amount of customers, correct?

    Hey Joshua,

    Thanks for replying back and providing additional context :)

    I agree that it would also be good to have a Windows run-through of these steps. I'm going to follow-up with our documentation team to see if we can get this article updated.

    Thanks for taking the time to share this with us!
