    • Receiver for Mac
    • Receiver for Windows
    • StoreFront

    Symptoms or Error

    Windows, Mac OS X, and Linux users cannot access desktops and applications from Receiver for websites using Mozilla Firefox 26 or later. When a Firefox user clicks an icon, the Receiver for website displays a spinner for a few seconds, but the desktop or application does not start and no error message is shown.


    Solution 1

    After clicking on a desktop or application on a Receiver for website, users must click the Plug-in icon in the Firefox address bar to allow the Citrix Plug-in to run.

    Alternatively, the Receiver for websites can be modified to display the message in the screen shot during the logon process to prompt Windows and Mac users who have not activated the Citrix plug-in within Firefox.

    Complete the following steps to modify a Receiver for website to prompt Firefox users to activate the Citrix plug-in:

    1. Download the .zip file attached to this article.

    2. On the StoreFront server, locate the contrib directory for the Receiver for website, which is located at C:inetpubwwwrootCitrixstorenameWebcontrib.
      Storename is the name specified for the store when it was created. If there are no customized files in the contrib directory, extract the contents of the .zip file to the directory to overwrite the existing files. If there are customizations, extract the files to another location and manually merge their contents into existing files to preserve the customizations.

    1. Repeat Steps 2 for any other Receiver for websites on your StoreFront server.

    2. For multiple server deployments, use the Propagate Changes task in the StoreFront administration console to update all the servers in the server group with the customizations.

    Solution 2

    Repair the Online Plug-in installation through Add/Remove Programs. If this does not resolve the issue, copy the following files to the <System Drive>Program FilesMozilla Firefoxplugins directory, from the same directory on a working computer:

    • CCMSDK.dll
    • cgpcfg.dll
    • CgpCore.dll
    • confmgr.dll
    • ctxlogging.dll
    • ctxmui.dll
    • ICAClObj.class
    • icafile.dll
    • icalogon.dll
    • sslsdk_b.dll
    • TcpPServ.dll

    Problem Cause

    Cause 1

    New restrictions on browser plug-ins, including the Citrix Plug-in used to access desktops and applications, were introduced in Firefox 26.

    Cause 2

    DLL files that are part of the Citrix Online Plug-in for Windows 12.x, or earlier versions, might have been altered or removed.

    Clear the 'Do not save encrypted data to disk' Option
