Steps to reproduce:

install new 78RC1, setup account by the dialog window that comes up.
choose manual, insert info for account without security, press fertig (continue?)

a warning panel comes up where I need to confirm that I know the risks without encryption.

Actual results:

OK button is outside the viewport on a 22 in screen with TB installing with its default screen size settings. I see about 2mm of the ok button.

There is a scrollbar, so bug repair is not high priority, but for new users, it looks bad

Using English?

Could u pls attach a screenshot (black out private data)?

can't do screenshot right now. If you refuse TLS, you get an extra warning in a dialogbox (red background), where you need to check a box before pressing ok. I mean that dialog

Magnus, TB in German. It seems to happen on first start only. But there are other UI problems that go away after second start (see my other bugs of today, e.g. missing folder pane, no calendars displayed), so that may be related. Wayne implied those problems might go away after restart, what they did

I'd suggest to put this as WONTFIX as I started working on bug 1664179 (move account setup in a Tab) targeting the next ESR.
Also, we didn't have any duplicate reports about it, so it seems to be kind of a unique edge case.

makes sense. thanks
