Videos don't have sound on Citrix
If you are on a Citrix Server on Windows, you may have problems with sound when you play videos on Firefox. This is due to an issue with increased security restrictions and we are working hard to resolve this.
In the meantime, you can reduce the sandbox security level by following these steps:
In the address bar, type about:config and press EnterReturn.
- The about:config "This might void your warranty!" warning page may appear. Click to continue to the about:config page.
- Search for security.sandbox.content.level, double-click on the preference and set its value to 1.
- Restart Firefox on the remote device.
