Moved from #185:

I have tried going to about:blank to see maybe it needs to be allowed or something, well nothing shows up on the matrix; however when you click on the matrix you find that the last website used is still in the "buffer" if you will, so what's going on? (see picture)

So that in itself is weird to say the least but the fact that access to about:blank by the other extensions is being so aggressively blocked without the ability to whitelist it or even without any explicit settings that interfere with behind-the-scene actions. So what's happening there? (see example)
