HELP! Images not loading and Firefox taskbar icon is a white file.

I went through all the suggestions in the image not loading help page and same with the add ins and nothing helping. The images load fine on Google Chrome so I know it's not the site. It might just be Adobe Flash images, but that's as far as I know how to pinpoint.
As far as the task bar goes, it's just a while file icon instead of the Firefox one. It doesn't bother me, but I just thought it might be related.
I'd appreciate any help! Anybody! Thanks,
Stef

What do you see if you right-click the area where such a missing image should be?
Is that a context menu for images with "View Image Info"?
Are there any icons on the location bar that plugins are used or mixed content is blocked?
If images are missing then check that you do not block images from some domains.
*Press the F10 key or tap the Alt key to bring up the hidden Menu bar.
Check the permissions for the domain in the currently selected tab in "Tools > Page Info > Permissions"
Check "Tools > Page Info > Media" for blocked images
*Select the first image link and use the cursor Down key to scroll through the list.
*If an image in the list is grayed and "<i>Block Images from...</i>" has a checkmark then remove this checkmark to unblock images from this domain.
Make sure that you do not block (third-party) images, the <b>permissions.default.image</b> pref on the <b>about:config</b> page should be 1.
Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.
Make sure that you allow pages to choose their own colors.
*Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"
Note that these settings affect background images.

There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

  • Background CSS images not loading in firefox when using a CDN

    Hello,
    I am having trouble getting CSS background images to load in Fire fox when using a CDN.
    Here is a description of the problem:
    - Everything works fine in Chrome
    - Any images loaded through CSS do not load in Firefox (they load in chrome) when i have the CDN enabled.
    - Other images / custom fonts appear to load fine with the CDN enabled
    My setup:
    - wordpress 3.8
    - CDN - Rackspace Cloudfiles synced with w3 total cache plugin (using the 'origin push' configuration)
    - using Cloudflare (mozilla appears to load the site fine while cloudflare is active)
    More about the problem--
    I suspect that the problem has something to do with the htaccess file redirecting some urls or something-- but im not quite sure what to do about this.
    Has anyone encountered this problem before who can offer some insight?
    thanks

    Hi pvijeh, is that the explanation for a security error? I'm having trouble understanding the context.

  • Images not Loading in Firefox

    I've got some trouble with loading images since flex 3 (and still with flex4).
    In my app I've got several Image tags meant to display jpeg files as follows:
         <mx:Image x="594" y="40" width="400" height="250" id="img_preview" horizontalAlign="center" autoLoad="false" />
    These images are supposed to load an url on runtime which I get from a dataset by means of an rpc:
         img_preview.load( thumbURL );
    Now the problem is that this works just fine on locally - but when I put the release build (or the debug-build) onto the web,
    I just get the missing image icon. This problem so far seems only to occur in firefox, since for example safari or ie working with
    the exact same file just as intendet.
    Ignoring the fact everything works everywhere else I checked the image urls, response headers for the images when loaded
    directly and so on - but found no errors.
    The images urls are absolute from the same domain as the flash movie and an appropriate crossdomain file exists for other
    reasons as well.
    Searching a little further by means of wireshark and firebug I found the flashplayer not opening any connections to the
    server, allthough I'm not quite sure if it's my inability to find the connection or the flashplayer who just want's to bug me to death.
    Any help would be greatly appreciated since I already lost SO MUCH TIME on this..

  • Please help - Images not loading in Safari

    I've been a Mac user for about 7 years now, and I'm stumped. Literally overnight Safari started acting up... and now no images on webpages will load. The pages load fast per usual, and all the text is there. Other than the images not appearing everything else appears normal. I've run Cocktail, done system checks, ran Tech Tool - pretty much everything i can think of without calling Apple Care. Does anyone have any ideas as to what the problem might be and how I can fix it?
    Thanks very much for your time and help! I really appreciate it, and would love to get this solved - it's driving me nuts!

  • FireFox images not loading in local folders (firebug error-Failed to load given URL)

    I am having difficulty when developing websites in local folders (Windows7 computer). The webpages I make are showing images in IE9 & Chrome but not FireFox (nor Safari nor Opera).
    In FireFox I get Firebug "Failed to load given URL" prompt.
    I am using html5 & external linked css stylesheet & the html/html5 & css code validates.
    I have tried using rel path ie images/image.gif & absolute path references ie C:/RPD_Programming/RPD WEB/amwcsnew/index.html
    and have tried using % to eliminate whitespace in references but I cannot get FireFox to display images!!
    This has been a problem for me for around 2 weeks now & is very frustrating. Some website code/templates I have downloaded from the internet display the websites properly (ie load images fine) when I open them locally in FireFox. Why does my code not allow the images to load in FireFox (paths/permissions/other issue??). How can I fix this?
    Here is example css & html5 not displaying images from local directory in FireFox (fine in IE9 & Chrome):
    style.css
    /* CSS Document */
    /*Basic Reset*/
    margin:0;
    padding:0;

    NB
    Is there a FireFox guide/manual in pdf format available anywhere? I have not found one yet & a FireFox reference might be useful!

    You need to use file:// as the protocol instead of C:/. The latter may never work (C:\ might).
    Where is the main HTML located ?
    Easiest if to store the images in a sub folder of the location because you can't go back via ../ beyond that root location for security reasons.

  • When I open firefox 4 beta the webpage does not load and i am unable to click on any buttons or access menus

    This has only started happening today. When I start firefox 4 beta it opens and begins to load my homepage (google.co.uk) but the page never fully loads and firefox freezes. I am unable to click on any buttons on the navigation bar or access menus. Keyboard shortcuts are also unresponsive.
    All that I am able to do on the browser is to use the three window buttons in the top right of the screen (minimise, maximise and close).
    After closing the window if I try to open it again I get a message saying that Firefox is already running, but not responding. Once going into task manager and stopping firefox under the processes tab and then restarting firefox the window again freezes as soon as it opens.
    I have tried restarting my computer and reinstalling the beta but with no success. I am still able to use firefox 3.6.13 as well as chrome with no problems.
    Any help would be much appreciated

    I had this too. Starting firefox in safe-mode and disabling all add-ons solved the problem. After re-enabling all add-ons did not bring back the problem.

  • PDFs do not load in Firefox, they do when I'm in Safari. If I'm on a website and I click on a pdf link, nothing happens. It has happened from multiple sites.

    PDF files do not load in Firefox. I click on a link for a PDF and nothing comes up. It happens at every website. I've been using Safari because PDFs open up there just fine. I have all the updated plug-ins, etc. and checked to make sure everything on Firefox was updated. I'm on a MacBook Pro, 10.7.3. I've never had this problem before.

  • Videos will not load in Firefox only. Have reinstalled, restored, etc.

    Videos (from YouTube, Facebook, websites, etc.) will not load in Firefox. I've tried reinstalling Firefox, restoring all settings to default, disabling all addons, extensions, etc. When I try to load a video, a dark rectangle appears where the video should and my cursor just shakes. In Chrome, Internet Explorer, etc. the videos load and play with no problems, no hesitation, so it must be some setting or some bad file with Firefox, but I feel like I've tried everything.
    I'm using Windows 7 on an HP laptop. I've checked my Firefox settings against those on my desktop PC and can find no variances. This problem is driving me mad, so please help.....
    Thanks.

    Hello,
    Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
    You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
    Then perform these steps:
    *Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
    *In the Firefox options window click the ''Advanced'' tab, then select "General".
    *In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
    *Now, restart Firefox and see if the problems persist.
    Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
    * [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
    * [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
    You can also disable hardware acceleration in Flash: <br> <br>
    Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
    To disable hardware acceleration in Flash Player:
    #Go to this [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues Adobe Flash Player Help page].
    #Right-click on the Flash Player logo on that page.
    #Click on '''Settings''' in the context menu. The Adobe Flash Player Settings screen will open.
    # Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. <br/> <br/>[[Image:fpSettings1.PNG]] <br/>
    # Remove the check mark from '''Enable hardware acceleration'''.
    # Click '''Close''' to close the Adobe Flash Player Settings Window.
    # Restart Firefox.
    This [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player Help - Display Settings page] has more information on Flash Player hardware acceleration, if you're interested.<br> <br>
    Did this fix your problems? Please report back to us!
    Thank you.

  • A URL will not load in Firefox (it does nothing) but will load in Safari; some other URLs also have a similar problem.

    In Safari with the above website, I cannot "View Source". Also, I have the same problem viewing images of patents at the USPTO, again probably a similar problem. Perhaps the web address isn't HTML but is an image format not supported by Firefox. Perhaps there is a plug-in or add-on that will be able to read the image, but should probably be included in the main Firefox release since it seems to be fairly common.

    A twitter widget on my website will not load in firefox but will load in every other browser I've tried. I have tried several versions of firefox. Here is the code I am trying to run:

    type: 'profile',
    rpp: 5,
    interval: 6000,
    width: 'auto',

    theme: {
    shell: {

    hashtags: true,
    timestamp: true,
    avatars: false,
    behavior: 'all'
    }).render().setUser('ShawnC4Real').start();
    </code>
    And the first thing I checked was that scripts were enabled.

  • TOC, Index, Search content not loading in FireFox 3.0 +

    Hi,
    I have created from RH 8 a merged Webhelp system (1 master, 2 children - based on Peter Grainge's posted procedure). It works fine from IE, and on my system, from FireFox 3.0 and up.
    The problem is, that when deployed at the customer's site, the TOC, Index, and Search content does not load in FireFox. All frames display (Nav, contents, and the top frame), but the content for the TOC, Index, and Search does not load.
    This only happens at the customer site. The webhelp system works okay in IE.
    I have checked and we are running the same javascript version, have the same security settings in FireFox set.
    I looked on Peter's site and implemented the redirect fix for FireFox that he has posted, but that hasn't seemed to fix the problem.
    They aren't running any special toolbars (like Google toolbar). I am checking on add ons.
    Does anyone have any ideas on what else I might check or better yet what might be causing the problem?
    Thank you,
    Tannis

    Willam
    A merge will not work properly unless all the projects have been generated once. After that it should not matter that a project is missing, indeed simply not publishing one of the projects to the server is one of the features of merging making it easy to supply different customers with different content.
    I wonder if the problem you saw was because that project had not been generated.
    Tannis
    Sorry, the reference to AIR help was because you mentioned Snippet 141 which is AIR specific. I didn't look further back in the thread.
    You said that the start page of a child project opens the tripane window with the default topic but you do not get the TOC etc. That rules out the merge being the problem. I am inclined to the view that the server is the issue so get your client to load the published output from my merge demo as that is a known quantity. Ask them to open each child project in turn and then finally the merge.

  • Images not loading in repeat regions

    I'm a newbie to using repeat regions, but got it working just fine. When I test in Live View, everything looks great, but when I test in a browser, the images are missing. The actual image file name is being added using php to the image's path. I checked in the browser source code and the path name is coming out correctly. As a test, I just added in one of the images manually above the repeat region. Not only did it appear fine, but suddenly the same image in that repeat region appeared! It must be an issue of not loading images. Is this a bug, am I doing something wrong, or do I need to add a script to preload images ahead of time?
    Here's part of my php code. The images are obviously store in the images/films folder and I'm just adding in the file name from the database:
    <?php do { ?>
              <div class="film">
                <img src="images/films/<?php echo $row_rsFilms['still']; ?>" width="178" height="100" />
                <h3 class="filmtitle" ><?php echo $row_rsFilms['filmTitle']; ?></h3>
            </div>
              <?php } while ($row_rsFilms = mysql_fetch_assoc($rsFilms)); ?>
    Here's the offending page: http://www.riversidefilmfest.org/filmguide.php.
    You can see the image I've added in manually which allowed the same image to appear successfully in the first record.

    Thanks Justin....
    This is for author/publish and it should be not the issue either the CQ instance is author or publish.
    Let me give you some more input.
    In CQ 5.4 the background image loading properly and image location is at  \etc\design\..\us\en\images
    And the following css just works fine.
    background: url("../../images/company.png") no-repeat scroll right -27px transparent;
        color: #232323;
    But same piece of code not working in CQ 5.5.
    We found in CQ5.5 some unnecessary urls appending to images and that makes the URL invalid.
    As per my understanding CQ5.5 should support backword compatability i.e. CQ 5.4 components should work fine in CQ 5.5.
    Please help me with this.Thank you.
    Thanks & Regards,
    Kumar

  • Images not loading consistently

    Hi,
    we have an J2EE application which has been deployed in production server. The specs are:
    Server OS: Sun Solaris 9
    Web Server: Resin pro-3.0.14
    Application Server: IBM Websphere Express 6.0.0.1.
    The problem is sometimes the images are not loaded, but if we refresh the page or use back button and click again or use forward button again, the images are loading. Sometimes the javascript as well as the css files are also not loaded.
    But the peculiar problem is that if we are in a LAN connection, everything is working fine. But if we have a static IP or browse in a internet browsing center or browse from home, then this problem occurs.
    I am at complete loss over this issue. Any help would be appreciated.
    P.S. The application includes jsp, html, java classes, EJB and DB2 database.
    Thanks in advance.

    I am also having similar problem. In my case, I have a simple web application made of html and jsp. My html is trying to load some images from folder webapps/example/images. The code I have used is <img src="images/logo.jpg" width="500" height="70">.
    The problem is only 1 or 2 images gets loaded and rest are blank. Can anyone help on this. If one image is loading properly why can't the rest do the same if all are present in same folder.
