[Pkg-chromium-maint] Bug#852398: current behavior stops security extensions

[k_f]

The current behavior is really, really bad since it exposes users, who 
thought a little of their privacy by installing privacy extensions like 
privacy badger (EFF privacy extension), no-script, ad-blocker or other 
extensions like that to the websites and ad networks. Next time you do 
something like that please disable JavaScript and all other Plugins (no 
video loading)
