This causes problems for a customer.
Can you give more information? what exactly does the customer want?
Basically customer is asking for the right click context menu to be completely disabled. No back/foward actions as demonstrated by the video above.
You can completely disable the context menu in content with this in an overlay:
Ok, overlay. I'm interested to know more / implement this. :)
This line can just go in the existing webconverger.xul.
Yes, in the guy here: https://github.com/Webconverger/iceweasel-webconverger/blob/master/src/webcfullscreen.xul the fullscreen variant. What's this magic line look like?
Ha. I didn't realize the line didn't come through :)
<tabbrowser id="content" contentcontextmenu=""/>
