649203 - Navigation toolbar stretches vertically after adding or removing a bookmark

Status: RESOLVED DUPLICATE of bug 640158

(Firefox :: Toolbars and Customization, defect)

Description

[ttrv3]

User-Agent:       Mozilla/5.0 (Windows NT 6.0; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Windows NT 6.0; rv:2.0) Gecko/20100101 Firefox/4.0

After adding a page as a bookmark, I noticed that the navigation toolbar was larger than it was before. NOTE: THE WEB PAGE IS NOT AFFECTED. ONLY THE NAVIGATION TOOLBAR IS STRETCHED. I open a new tab, and realize that it isn't a page-specific issue; it pursues all throughout my browsing in the window. I open a new Firefox window, and the bar is back to normal, until I click on the bookmark star from the awesome bar.  I then opened another new window, tried the control-D (add page as bookmark) shortcut and the bookmark manager method of adding and removing a bookmark; it happens again. 

Reproducible: Always

Steps to Reproduce:
1. Click the add bookmark star from Awesome bar in new window.
2. Control-D keyboard shortcut in new window.
3. Click 'bookmark this page' in Bookmark Manager, in new window.
NOTE: bug can only be reproduced in a new window.
Actual Results:  
The navigation toolbar stretched again.

Expected Results:  
The toolbar would NOT stretch.

XMarks browser extension installed.

Bookmark toolbar enabled. Tried again without it, and the bug persisted.

Does NOT reproduce in safe mode (with add-ons disabled). My gut feeling tells me its Xmarks...
