Dear Mozilla Community,

Our company use a web application whiches we can connect to customer servers via RDP (Remote Desktop Protocol). The web application uses Spark Gateway. The problem is that if we use the web application with Firefox, we can't use clipboard function.

The error codes in the browser console:

Uncaught DOMException: A network error occurred.

  httpGet https://application.ourcompany.com/hosts/gateway/html/hi5core_min.js:68
  getClipData https://application.ourcompany.com/hosts/gateway/html/rdp_min.js:146
  onCopy https://application.ourcompany.com/hosts/gateway/html/surface_min.js:120

If we use the application with different browser (like Edge or Chrome), we can enable the clipboard on the browser. If we enable the clipboard access for the site (https://application.ourcompany.com), the copy/paste function works well. The problem is that we cannot find enable clipboard feature in Firefox.

My quiestion is, how can we enable the clipboard in Firefox for our (webapplication) site?

Thank you so much for the help!

Best Regards Gabor

There is a preference in about:config but its default value is true so perhaps an add-on or some special configuration file changed it. dom.event.clipboardevents.enabled The error message suggests that a site setting is preventing the clipboard from working.
