Editor.singleLine.pasteNewlines
From MozillaZine Knowledge Base
Jump to navigationJump to search
Background
Single-line text fields do not allow users to input newlines. Pasting content, however, poses a problem: what happens if pasted content contains newlines? This is often handled differently on different platforms. This preference determines what happens to multi-line content when it is pasted into a single-line text field. The area for email addresses is affected by this preference. Changes are valid only for succeeding windows.
Possible values and their effects
