Break On XHR

Jan Odvarko, odvarko@gmail.com

This test is intended to verify Conditional XHR Breakpoints support within the Net panel.

  1. Open Firebug and select the Net panel.
  2. Click the Execute Test button.
  3. There should be a new request displayed in the Net panel.
  4. Click on the breakpoint column on the left side to create a new breakpoint for this request.
  5. Click the Execute Test button again.
  6. The debugger must stop execution, the Script panel must be selected.
  7. Press Continue and go back to the Net panel.
  8. Left click on the breakpoint to open a condition editor and set the condition to param == 1.
  9. Click the Execute Test button again.

Add #8, the same request is there twice and so is the breakpoint. Just pick one of them.
