javascript - Chrome Dev Tools Cannot Expand Iframe contents - Stack Overflow

As seen in the picture above, this iframe contains an html file but now its contents cannot be expanded. Before Chrome 56 I have been able to expand the contents, now I cannot. Is there something else I must provide for it to expand now?

  • What extension does the ID in the iframe src correspond to? I can't find it in the Chrome App Store. – user149341 Commented Mar 20, 2017 at 19:36

Chrome now runs iframes in separate chrome renderer processes to optimize performance.

To view such an OOPIF:

  • METHOD 1. Right-click the iframe contents on the page, then Inspect to invoke a separate devtools window.

  • METHOD 2. The uping devtools UI (see crbug./652783) lists such iframes in the same devtools under the main page DOM in Elements inspector:

    This work is in progress and available behind an experimental feature in DevTools.

    1. Enable "Developer Tools experiments" on chrome://flags, and restart.
    2. Open DevTools Settings, go to Experiments tab, and press Shift 7 times.
    3. Check "Auto-attach to cross-process subframes."

    Note, on Windows you may see a sticky keys dialog on the 5th tap, just close it and continue.

Test site with an iframe: http://csreis.github.io/tests/cross-site-iframe-simple.html

Not sure if this helps anyone but I had the same problem. It turns out if you just scroll down the Elements window you'll see the frame right at the bottom, took me a while to figure that out.
