Fixed two vdc link related issues; however I could not observe the problems that you described in relation to Chrome. Tested on the latest available version which is 54.0.2840.59 (64-bit)
The new tabs/windows get blocked by the popup blocker unless you allow them explicitly, but you do get the notification that a popup attempt was made. Unlike you described, the links were not empty and it behaved just like on Firefox.
Problems fixed:
- contexts= parameter was used instead of context=
- when only the zone or the group, but not a particular zone scene were selected, then the forwarding was done to "activities" instead of "customactions"
