Interesting glitch: Firebug breaks Set Featured Image modal in Post Editor

  • When editing a post with firebug console open, clicking on “Set Featured Image” fails to load the modal on the first click. On the second click, it’ll load the modal, but it will be blank. It will remain blank even after closing firebug and reopening the modal.

    STEPS TO REPRODUCE:
    1. Load the post editor for any post
    2. Open Firebug window
    3. Then click on “Set Featured Image”

    The first click will not open the featured image modal box. Click it again and the modal will open but will be blank. It will remain blank even after closing firebug and attempting to reopen the modal. Interestingly, if you open the modal first, you can then open/close firebug and open/close the modal without problems.

    MY COMPUTER:
    Windows 7 64 bit
    Waterfox 33.0.2 (Firefox 33 recompiled for 64 bit)
    Firebug 2.0.6

    WAS ABLE TO REPRODUCE ON:
    Three completely different sites on three totally different environments (a 4.0 site in a sandbox, and two different 4.0.1 sites on different live servers.)

    I came across this error while trying to add functionality to the featured image editor. Not sure if this is a bug or a problem with WP, Firebug, or just my setup. Anyone else able to reproduce this error?

    If it’s Firebug actually triggering the problem, and it works just fine without Firebug, I’d recommend reporting it as a bug to Firebug: https://code.google.com/p/fbug/issues/list

    Not having this issue myself.

    Windows 7 64 bit
    Firefox 33.1
    Firebug 2.0.6

    Thanks guys. Did a little more homework and experimenting on other computers.

    Bug *not* reproduced on:
    Ubuntu 14 + Firefox 33 + Firebug 2.0.6
    Win 7 64 + Firefox 33 + Firebug 2.0.6

    So I’m starting to suspect it may be some interaction with Waterfox and Firebug, or it could be something stupid with my machines. Either way, it’s rather strange that a dev console would interfere with a site. Never seen that happen.

    Well, dev consoles are supposed to interfere with sites. You can execute commands, tweak HTML/CSS, tons of fun stuff. ??

    Firefox is pretty consistent across platforms, so given the above, I’d suspect Waterfox to be the source of the problem.

    Of course dev consoles are there to mess with things, but I’ve never seen one break something merely by being opened. Usually it’s the next step of actually using the console to mess with things that causes brilliant and amusing failures.

    Yeah, what I mean is they inherently *can* mess with things, so given a browser conflict, it is entirely possible that their messing with things could be triggered by something as simple as opening it.
