633480 - "undefined" appears in location bar when hovering over bookmark

Status: RESOLVED WORKSFORME

(Firefox :: Address Bar, defect)

Description

[Stuart Orford]

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0b11) Gecko/20100101 Firefox/4.0b11
Build Identifier: Mozilla/5.0 (Windows NT 5.1; rv:2.0b11) Gecko/20100101 Firefox/4.0b11

If I open a new window and hover over a bookmark, the bookmark URL displays in the location bar as expected; however, "undefined" also displays, over the words "Go to a Web Site". This only happens in the first blank tab in a newly opened window; as soon as I navigate to a page, or open a second tab, the behaviour stops, even if I then close all the tabs and go back to a single blank tab. A blank tab torn off from an existing window also doesn't have the bug. Same behaviour in safe mode.

Reproducible: Always

Steps to Reproduce:
1. Open a new window.
2. Click in the page to remove focus from the location bar.
3. Hover over a bookmark.
Actual Results:  
The location bar displays "Go to a Web Site" and "undefined" overlayed on each other (on the left), and the bookmark URL (on the right).

Expected Results:  
The location bar should just display "Go to a Web Site" and the bookmark URL.

Can you reproduce in Safe mode (http://support.mozilla.com/kb/Safe+Mode)? it's possible you have a add-on causing that issue
