OK, I'm running Fennec 19.0a1 and latest NSA++

.
Initial observation is that I can't tell how I'm supposed to interact with NoScript on the page. There's an icon, which unfortunately grows to massive proportions when I zoom in on the page, and when tapped, it brings up a box showing the current site and icon (in this case, informaction . com and the blue S indicating 'all scripts allowed on this page'). But then what? Tapping on that box doesn't seem to do anything.
Update: Have now tried StartPage (startpage . com), and tapping on the icon in the box allows me to cycle between default, trusted, and untrusted. Not bad. No sign of temporary permissions, but I can live without them.
What kinds of issues need investigation?
