HTTP Archive Reader

HTTPA Archive Reader allows you to read files exported from Firefox’s Firebug Net Panel via the export add-on. I created this add-on because the only way to open the archives was via a website and although the core functionality is great the ability to do further analysis and extract data

Why? I like firebug and wanted a way to manipulate the exported data that it provides.


  • Supports multiple logs being opened at once.
  • Does not change or update the log file.
  • Reads and validates HTTP Archive format logs;
  • provides a list of log structure errors.
  • Generates a timeline for the captured data showing all types of transactions (wait, request, response, etc)
  • Clicking on a timeline item will allow you to view all the data collected by firebug Net (Timing, request, response, cache, etc);
  • Most lists have full copy to clipboard functionality, supporting plain test, html table, comma separated and tab separated formats.
  • Most list items can be double-clicked on to open a zoom-text feature.
  • Selected content items timeline is zoomed on screen;
  • The timeline display can be hidden/shown, allows optimal space for reviewing a content items characteristics.
  • Analysis of the net data, producing chats of:-
    • Data throughput over time (Send, Receive and Cache)
    • Size Chart (Largest 20 content items)
    • Response Breakdown – Longest (20 content items that took the longest to complete)
    • Response Breakdown – Slowest (20 content items with the lowest throughput)
  • Charts have Copy, Save as Image and zoom/pan capabilities.
  • Content analysis tools including:
    • W3C Standards Check
    • W3C Accessibility Check
    • Javascript Check
  • Content analysis allows results filtering, text-zoom including response source code view.
  • (New Summary pannel on main window showing a comparison of total time for all open archives (Double Click the bar to view the archive).
