Comment 92 for bug 195698

Partly on topic, about dialog vs. URL edit control:

I was always annoyed by the fact that a dialog popped up by one tab prevented me to access the other tabs. Example:
You read instructions on one tab :
 - tab1: "visit this URL"
 - you open that URL in new tab
 - tab1: "click this link"
 - you click the link on tab 2
 - an authentication dialog appears
 - tab1 say : "enter x and y as name and password", but YOU CANT read this, since the dialog blocks you from switching to tab1
