Make Firefox Display Large Images Full Size

Firefox resizes large images by default to fit in the browser window. This can get really annoying if you are browsing a lot of large images.

To see this in action, you can click the link to the really nice Ubuntu wallpaper. You’ll notice that you have to click on the image to show the full size version.

To change this setting, follow these steps:

  • Type about:config into the address bar in firefox.
  • Type in browser.enable in the Filter bar and hit enter
  • When you see “browser.enable_automatic_image_resizing”, double click it and the value should change to false, as shown.

    Thanks for this. I am always saving pics (seriously my pic folder is 653mb), and this will make things a bit faster.

    Thanks, this used to be a regular option. Who decides to take our control away from us anyhow?

    Thanks to whoever published this :). VERY helpful.

    Thanks Geek!

    I agree with Rob– I was surprised to see that I couldn’t change this in the preferences.

    O happy day! Wow, I’m really thrilled about this information. It’s just what I always wanted.

    Is it just me or is the resizing of large images by default actually the best option?
    It gives you a chance to see the whole thing first, then if you want to see it at 1-1 resolution you just click it.

    I already know what the pic looks like, because I clicked on the thumbnail in the gallery.
    After clicking on the thumbnail, I want to see the actual pic and save to hd if the quality is ok.

    Looking at this in the opposite way…is there any way of fixing the max size image ff displays? For example, I want to set ff to display images at a max of 1280×1024, forcing it to resize larger pictures so they all fit on my screen and I don’t have to scroll left-right.

    For some reason, although my browser.enable_automatic_image_risizing is set to true, it doesn’t work!

    Great post! Glad to know this finally.

    Related question – Is there a way to force the browser to show a large image at 100% through html or css, so that everyone viewing sees it at 1:1?
