QR code selection interface improvement

[AfroThundr3007730]

Describe the bug:
Two things:

• In the QR code selection UI, the crosshair is very difficult to see and blends in with the background
• There is no way to abort the selection (preferably with esc key), and you have to make a dummy selection to clear it

Platform:

• Browser: Firefox
• Browser Version: Nightly
• OS is Debian Testing x86_64

Right click mouse should abort the selection. At least it works in Chrome. Could you verify it in Firfox?

[AfroThundr3007730]

Ok, that does abort the selection, but opens the right-click menu. Would you consider adding the keyboard shortcut as well?

@AfroThundr3007730 sure, it makes sense.

@AfroThundr3007730 you might want to test in stable and report that in Bugzilla, I don't get a right click menu when the overlay is up. I'm running Firefox 63.0.3 on Fedora 28

[AfroThundr3007730]

Just verified in Firefox 60.3.0esr on Windows 10 1803 x64 (at work) that the right click menu still appears when canceling the overlay with the mouse.
