  • ....and this for quite some years by now. Been using this little tool ever since it was launched. Thank you CHRISPEDERICK(!) for this contribution!
  • On firefox 48 javascript flag is gray out... and won't change status even if I change website, another my friend has the same issue on windows 10 with firefox 48...
  • Benutze es selten, bin dann immer wieder überrascht von der Anzahl an Werkzeugen. Danke!
  • Deleting domain/path cookies is not working in new version!

    Upd.: Thank you for reply and upcoming fix.
    I just submitted version 1.2.11 for approval by Mozilla which contains the fix for this.
  • Can you fix it so that it works again please???
    This should be fixed with version 1.2.10.
  • Please fix this from last update for FF, can't live without it.
    This should be fixed with version 1.2.10.
  • "Display Style Information" functionality is broken since the last update. Please fix it.

    UPDATE: Thank you so much for fixing it and for the great plugin you have developed. Just changed the rating to 5.
    This should be fixed with version 1.2.10.
  • After update from 1.2.5 to 1.2.9, display style information anymore display empty informations
    For exemple :
    /* Ligne 66 */
    h1, h2, h3, h4, h5, h6
    {
    }
    This should be fixed with version 1.2.10.
  • Здравствуйте.
    После последнего обновления перестала корректно отображаться иконка валидатора js.
    Они отображаются с белым фоном в данный момент.
    Исправьте пожалуйста.

    Такую же проблему заметили судя по всему и другие пользователи:
    *
    Please correct display text beside icon in navigation bar same in previous version 1.2.5.1. In 1.2.9 is wrong below icon.
    *
    This appears to be caused by the Classic Theme Restorer extension: disabling that should fix the issue. I'm looking into if this is something I can fix on my end, but it may be something that the author of that extension has to fix.
  • New update: don't work " display style information" in CSS. I see only clases without behaviour.
    For example:
    /* Line 1 */
    .stats-chart
    {
    }

    /* Line 1 */
    .dashboard .stats-chart
    {
    }

    Firefox, Win 10
    This should be fixed with version 1.2.10.
  • It's possible change my localization? Because portuguese brazilian the labels are quite big, I'd prefer English.

    This is the best plugin ever.

    Thanks.

    Sorry my English write.

  • Makes you wonder why? It is very easy to blame something that has been out there really long. Just want to report that on a Windows 7 machine and a GNU/Linux Debian system, no such problems. Keep up the good work!
  • When watching YouTube-videos with web developer activated they cause Firefox to be hang, stall and to be unresponsive. Every click (start/stop/fullscreen-toggle) takes about 5-10 seconds to react and I can't do anything else in firefox, when this happens.

    This makes Web Developer unusable and I recommend to disable and/or uninstall this addon until this issue has been resolved, which is probably never (Last updated: 29.04.2013 ...)

    TL/DR:
    This addon is dead and it shouldn't be used anymore.
    I'm working on a new release of the extension and one of the last issues to fix is the impact the extension has on YouTube. I'm looking for people to help me test possible fixes and if you are able to help please email me at website AT chrispederick DOT com.
  • I use Firefox 47 on Mac with WebDeveloper Addon, I noticed too that when I load YouTube page, video Firefox is very slow, not responsive and hang... It's must be fixed.

  • Have used this add-on for years, now it makes Firefox unusable if I happen to load a YouTube page. As is obvious, I'm not the only one to have observed this problem.

  • I was really upset that i couldnt use firefox when I've entered a youtube-site. It took a while to figure out, that this addon nearly stops my browser when I enter a youtube-site.

    Please fix it.

  • This used to be a great add-on. Now it grinds YouTube pages to a halt. Scroll down on YouTube video pages is very slow and often the browser window becomes unresponsive so you're forced to close it. Please fix it.

  • I am using this tool for years for my web development and web designs. Couldn't work without it. Only one simple question.... I needed to re-install my mac and i am trying to restore the Web developer toolbar preferences... where should i locate it? Thank you!
  • As a web developer I find this addon extremely helpful. It has so many features that help in so many scenarios. Need to disable browser caching quickly? Done with a toggle. Need to delete cookies? Also easy. Need to view response headers sent by browser? Yep it does that and much much more. Highly Recommend whether you're a professional or just starting out in web development.
  • very helpfull
  • I am using this tool and find very helpful, specially in Image and CSS information
  • No update so far to support jquery, bringing error and warning... This is really annoying.
