Showcase (?) does not work for some sites.

My problem is basically this: link text

Some sites are listed, some are not. It's like to happen in a random order. I tried to clean the cache, it did not work.

Any ideas?

The pages that sends a non-magasin or no.-cache header are not cached and therefore Firefox does not generate a thumbnail.

  • bug 756881 - new thumbnails tab is displayed does not (or old images posted) for Facebook, Twitter (sites using Cache-Control non-magasin)

(Please, don't comment in bug reports)

  • Single-pass does not work for Web sites after the last update of firefox

    Single-pass does not work for Web sites after the last update of firefox. This works in IE and Chrome and it works under windows (when starting the computer), but not with any website in Firefox.

    Firefox 30 spent some less commonly used "Always turned on" plugins "asking to activate. To check and change this to SimplePass, you can use the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click on Plugins. Then on the right, check the control on the right side of the SimplePass.

    You may need to exit Firefox and start it again before it takes effect.

  • Sound does not work for some Web sites

    Hello

    I can't listen to music on the following Web sites:

    http://www.cede.ch/en/music/?branch_sub=1 & View = detail & ID = 896510 & Branch = 1
    http://estastonne.bandcamp.com/album/live-in-Odeon-2011

    I use the first a lot, which is really annoying. I've already looked and I think that the problem has to do with firefox. I have a linux system. When I try to play music, I see the time meter that works perfectly, the only problem is: I have no sound. If I install firefox 25, I have no problem. With firefox 26 or 27 of firefox it does not work. With the same configuration (plugins for example) if I switch to firefox 25, all right. I tried clearing the cache, but it does not help. I have no idea more.

    If anyone has an idea that would be great!

    Thank you

    This looks like a problem with the player player of the second site.

    I don't know what flavor of Linux, this thread is running, but there is a problem with GSStreamer around the time 25-27 that has been activated.

    I'm looking into this site and see player video javascript. The GSStreamer is used only with html5 and h.264 and others have their own codec.

    After some research on this second site, its an mp3 file. It's called TralbumData which is a hack for streaming music bandcamp. They use the MP3 format to 128 for data flow. http://Bandcamp.com/help/audio_basics There is also no volume control.

    So to answer your question, it seems to have been something that has stopped working. Please make sure that your media player is updated if you update to version 27.

    The bug for this specific page is https://bugzilla.mozilla.org/show_bug.cgi?id=921714 which recommend to disable media.gstreamer.enabled, in the subject: config as well.

    That should solve the problem!

  • "Sweep left" does not work for some email notifications

    On some mail notifications, as documented works "sweep left" very well, but I'm still not clear what if any difference there is between 'X' and 'Clear' (see previous announcement) - I have recently several contradictory theories.  However, for SOME e-mail notifications, "left sweep" simply does not work - nothing happens.  I * think * it's maybe for 'complex HTML' messages, not 100% sure.

    Hi Doug

    As previously indicated, 'X' and are clearly part of the same key - typing will erase / reject notification from your list of recorded notifications.

    Also as previously indicated, there is a difference between alerts by mail in the list of alerts in the Notification Center (IE hitting swiping to the left on the alert) compensation and removal / rampage messages in the Mail application.

  • Present the online PDF form button does not work for some users

    Two online forms, I created in LiveCycle Designer 8.2 work very well for me. But when some of the users of my site clicking on the Submit button in a form, it just flashes and then does nothing. It's a standard transmission with a Mailto link button. The documents are PDF Version 1.7, and I use Acrobat Pro 9.4.5 and Reader 9.4. Suggestions for troubleshooting would be great.

    This form is activated with the form of rights to the player.  If the full PDF is presented, then the PDF file must be Reader enabled to operate the player.

    Another problem is that sending email is entirely dependent on the user's system.  There must be a local e-mail client installed and registered with the system.  Internet mail will not work.  This is the most likely issue.  Althougth there are other things that could be the problem.  You can consider using the Acrobat.com to distribute your forms.  This method gets around the question for most users.

    Other issues that could cause this problem are the version of Acrobat/Reader users as well as any type of system/security configuration funky.

  • SimplePass does not work for Web sites after the receovery system

    I recently did a recovery plant system overall condition,

    CW,

    You did not include the version of your operating system: Windows 7 I guess because you have been deported back to a very early version of the HP SimplePass.

    You must consider that you may have a version of your fingerprint driver that is appropriate (fairly recent) to run a newer version of HP SimplePass.  The fact that the old version SimplePass does not at all suggests that you run the version of the driver 4.3.118.0 - this version of the driver is not compatible with subsequent revisions of the SimplePass software.

    • Fingerprint drivers

    If your version of the driver (for your OS) is equal to or newer than those listed here, chances are that you can keep your current licence.

    If your current driver is older than the driver for your operating system,

    then: download and install yet the driver of fingerprints for your operating system.

  • Flash Player 10 does not work in some sites, works well in others

    Lately I had problems to visualize videos with Flash Player on many sites in which they considered much earlier. What I see is a solid black rectangle the size of the video screen. No player controls. Nothing. I looked at the code of the page, but found nothing out of the ordinary. The system on this machine is XP Pro with SPII, and the problem occurs whether you use IE 8 or Firefox 3.6.3. The screen showed 'about' that I had Falsh Player 10.0.32.18 installed on my system, so I downloaded 10.0.45.2 and installed, hoping that would solve the problem. Nope.

    Currently goes http://www.adobe.com/software/flash/about/ via either IE of Firefox watch I have correctly installed the version 10.0.45.2. The animation plays well in both browsers.

    Today one of my friends is a graduate of Temple University in the Japan, the graduation ceremony was broadcast live (03:30 in the morning my time). I couldn't watch it. This site has been http://www.tuj.ac.jp/graduation2010/video.html hosting site is UStream, specifically http://www.ustream.tv/channel/tuj-2010-graduation I can not all videos on UStream to open. All I see is a black rectangle. My friend's mother had no problem viewed the ceremony with Firefox on his laptop computer.

    Other sites that worked well recently but no longer ply videos at all on this system are Fox News and NBC News. I have no problem watching Al Jazeera news videos, but videos post on UTube. I have no problem, watch videos on UTube. BBC News videos will work also perfectly, as do many other sites videos. It makes no difference if I accept or block cookies on the sites that cnnot play videos. What is different on these sites than others?

    I read that two related discussions here, not a problem with sites loading Flash... and Flash videos does not not on espn.com in any browser , but none of them had any relevant help to my problem. Re: videos not working not not on espn.com in any browser Flash Re: Player does not start The second thread was a problem loading videos from ESPN, giving the site

    http://espn.go.com/video/category?id=3461971 for example. but I have no problem watching videos on this site or any other videos on ESPN. Instructions given in the first thread that is supposed to remove several files in the C:\WINDOWS\system32\Macromed\Flash folder, but I had none of the files lilsted.

    Is there something in my registry that needs to be changed? Is there something that my antivirus (Bitstream) program may have killed? I really want to solve this problem.

    I don't know anything about the jpeg encoder, but I do not see the code which makes no sense to me:

    Image resizedImage = null;
    
    int iWidth = image.getWidth(null);
    int iHeight = image.getHeight(null);
    
    // This code ensures that all the pixels in the image are loaded.
    Image temp = new ImageIcon(resizedImage).getImage();
    

    What is so as to create an ImageIcon from an image zero?

    int newWidth = (int)this.targetWidth;
    

    I don't see where actually use you this variable, then how the image does get resized?

    To learn more create a [url http://sscce.org] NBS, which illustrates the incorrect behavior and maybe someone will take a look.

  • CSS does not work for some reason any...

    Hello
    I use Dw MX and I use it back after having been there for a while. There are a couple of keys made here that may be important. First of all, I imported this site from Frontpage 2002 (it has been done initially in Frontpage 2003). Secondly, I am under Dw MX on Ubuntu Linux using CrossOver.

    So it is possible that this may be a problem of Linux, but it's a 50-50 as far as I know. In short, nothing that to do with CSS seems to work. I can't redefine a style Html - nothing appears. I tried to do and attach an external style sheet to get a picture in the background, and nothing is displayed. BTW, I do these especially for a model, but regular pages seem to have this problem as well.

    I can not even a background picture is displayed using the Page Properties.

    I am quite experienced with web programs; I did something like that for 6 years now. But here, I am puzzled, even if it is possible something in fair DW on me because it's been awhile. Also, I installed the MX 6.1 update.

    I appreciate any assistance.

    Thank you, Frank B.

    Murray, have you noticed:

    "First I imported this site.
    Frontpage 2002 (it has been done initially in Frontpage 2003). »

    It might be just stacking CSS rules at the top of the old rules of CSS, or even on top of
    HTML styles. It sounds like a code problem, not a problem of DW...

  • Whitelist config.xml does not work for some AJAX calls

    Hello

    Here's an excerpt from my config.xml file:

    http://www. .TV"/ >

    Here is the error I get: http://cl.ly/image/3r420g1Q2b1F

    You have to trust me that the fields are the same (in the AJAX call and config.xml). Indeed, this app works fine on the browser BB10, but not "wrapped" with WebWorks.

    What is strange, is that several other AJAX calls to the same area as planned work. I don't know where to look what could be the problem?

    Thank you.

    So first of all, the reason for which the application is refused is due to a known issue with URI invalid containing @ signs. Technically the sign @ is only a valid uri character forward as [email protected]/blah, and at other points should be % encoded.

    By your work around, the good work around would be to allow access uri = "" * ", which should solve this case."

    By disabling the security web, shall be carried out as a last resort, but your original implementation was correct except for one minor detail, the value should be 'disable' and NOT 'disabled', thus
