984094 - AJAX loaded JSON will be visible in sourcecode after using HTML5 history API

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Diego]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release)
Build ID: 20140212131424

Steps to reproduce:

I´m using AJAX in combination with HTML5 history api (pushState) in Firefox V27.0.1 / Windows 8.1.
So, this has the following effect: After you clicked on a link a script will be executed and the site will be loaded with AJAX and browser history will change correctly. But if you take a look into the sourcecode after the AJAX load, you will see the full JSON which was loaded with AJAX. This should not happen. It should appear the full HTML-file.

You can find a live example here: http://goo.gl/jO56hD
Navigate through the site with enabled JavaScript and click on rightclick -> show sourcecode after you navigated and you will see the JSON which was loaded from the AJAX.

This error occurs only with using HTML5 history.pushState and I think it´s a Firefox bug.



Actual results:

It appears the loaded JSON in the sourcecode instead of the sourcecode.
The DOM looks still fine, but the sourcecode doesn´t.


Expected results:

Nothing should change the sourcecode.

This problem also appears to corrupt the session history. If you open the test case, click any link, then close the tab, and then re-open it using History > Recently Closed Tabs, instead of getting the page back, you just get the last-requested JSON object. Something definitely is broken here.

Misfiled. Please reopen if this is still reproducible in a current version of Firefox, and (ideally) provide a minimized testcase demonstrating the issue. (Previous goo.gl link is dead.)
