User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7 (.NET CLR 3.5.30729)

(OS is actually Windows XP x64 SP2.)

I have 13 links in the Bookmarks Toolbar and usually have between 3 and 8 tabs open in Firefox.  I usually invoke one of those links by right-clicking on it and choosing Open in New Tab on the pop-up menu.  Behavior here is normal and expected:  Firefox adds a tab and open the link to the site.

When I click the little red "X" box to close a link opened in such a manner, however, something goes weird.  If my next action is to again right-click on a link in the Bookmarks Toolbar, the pop-up menu appears with all three Open... options and Properties grayed out.

Clicking somewhere else in Firefox corrects the problem and a new right-click shows the Open... and Properties options available.

Reproducible: Always

Steps to Reproduce:
1.  Right-click on Bookmark Toolbar link and choose Open in New Tab.
2.  View the site on the newly opened tab and close the tab with its red "X".
3.  Right-click on Bookmark Toolbar link again.
Actual Results:  
Open, Open in a New Window, Open in a New Tab, and Properties pop-up menu options are grayed and unselectable.

Expected Results:  
Open, Open in a New Window, Open in a New Tab, and Properties pop-up menu options should be black and functional.
