388371 - Text in URL bar moves because it has ligatures when host highlighted

Status: RESOLVED FIXED

(Firefox :: Address Bar, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

The text in the URL bar moves when the mouse is over the URL bar because we're using ligatures when rendering the text while the host is highlighted, but ligatures are not used in the normal rendering.

Steps to reproduce:
 1. load http://www.flickr.com/photos/dbaron/
 2. move the mouse over the URL bar and away from the URL bar

Actual results:
When the mouse is over the URL bar or the URL bar is being edited, ligatures are not used.  When the mouse is not over the URL bar and it is not being edited, the "fl" in flickr is displayed using a ligature, which makes the text narrower.  This means the entire URL bar moves when the mouse moves over or away from the URL bar (while it is not being edited)

Expected results: The text in the URL bar should not move when the user moves the mouse over the URL bar.

Sounds like a duplicate of bug 386759.

Probably, although kerning and ligatures are separate things that both affect the width of text.

(I hadn't found that when searching before filing this, somehow...)

The patch in bug 386759 should fix this.

This should have been fixed by bug 386759 for quite some time. Otherwise please reopen.
