About Citrix Receiver for HTML5 1.9

Nov 01, 2017

Citrix Receiver for HTML5 is hosted on StoreFront servers and enables users to access virtual desktops and hosted applications from a web browser. Resources delivered by XenDesktop and XenApp are aggregated in a StoreFront store and made available through a Citrix Receiver for Web site. With Citrix Receiver for HTML5 enabled on the site, users can access desktops and applications within their web browsers without needing to install Citrix Receiver locally on their devices.

When used in conjunction with the centralized customization and branding capabilities of the StoreFront 3.0, users of this Citrix Receiver for HTML5 release will receive a centrally managed app and desktop selection experience from StoreFront. This is the same consistent user experience that can be received by the Windows and Mac desktop Citrix Receivers and Chrome web Citrix Receiver when associated with the StoreFront 3.0.

New in this release

Enhanced clipboard support

Citrix Receiver for HTML5 we now supports HTML format in addition to plain text between client and a session. This support is useful for Office apps and browsers. Enhanced clipboard support is only available on Chrome and Safari browsers.

How does it work?

Prior to introducing this feature, Citrix Receiver did not support copying and pasting HTML-formatted text from a local application to another application (for example, Microsoft Excel) using the Paste Special feature. As a result, the targeted app (in this case, Microsoft Excel) would not retain its HTML formatting characteristics. 

At this relesae, you can copy HTML content and retain formatting; when copying a link in Chrome, a <img> tag is added in HTML format, which effectively allows you to copy images as well as text. This feature is richer than plain text, but does not work in all applications.

For this feature to work, you must add the following registry entry to the VDA:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard\Additional Formats\HTML Format

"Name"="HTML Format"


Using Registry Editor incorrectly can cause serious problems that can require you to reinstall the operating system. Citrix cannot guarantee that problems resulting from incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Make sure you back up the registry before you edit it.


For additional information about the issues resolved by the introduction of this feature, refer to support articles available on the Support site (CTX112063 and CTX086028).

Known issues

  • A session may crash while copying and pasting a large amount of data inside a session. Citrix recommends copying less than 10 MB of data when using the clipboard.
  • Citrix recommends that you use an absolute path rather than a relative path in File Transfer registry settings.
  • Citrix Receiver for HTML5 does not support cross language keyboard.
