Rated 1 out of 5 stars

about:ctp looks completely borked.
I can tap on the add domain button (barely because it's mostly out of the screen and I can't zoom) but that's about it.
It's impossible to successfully add the typed domain. The button always stays dimmed.
If you close the keyboard you can't get it back again no matter how much you tap the input field.
You can't cancel the operation.
You can't even navigate away from the page.
You can't even load another about: page until you restart firefox

This review is for a previous version of the add-on (1.4).
