#15718: Firefox popups disappears on first click

 To reproduce this bug:

 1. Visit https://pad.riseup.net/p/torbrowserbug
 2. When the popup about HTML5 canvas appears, click anywhere on your
 desktop, for example to switch window or switch tab.
 3. This first click doesn't do the intended action but instead closes the
 popup about HTML5 canvas without you acting on it.

 This also happens with other kind of popups, for example when installing
 and downloading extensions.

 I discovered this bug while working the UX of the Tails verification
 extension for Firefox
 (https://tails.boum.org/blueprint/bootstrapping/extension/) where I
 believe this bug could lead to great confusion.
