It seems to be working fine at my end.

Could you please provide the following details for debugging:
1. OS
2. Firefox Version
3. Open up console (Ctrl/Cmd+Shift+J), then right click a link. If anything is printed to the console, that particular message.

Update:
As a temp measure, I have rolled back the 0.0.4 changes. Please downgrade to 0.0.3.

Regards,
Bg Dam
