Status: RESOLVED DUPLICATE of bug 472343

(Firefox :: Bookmarks & History, defect)

Description

[steve_nelson47]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 (.NET CLR 3.5.30729)

I selected 800 of 3000+  bookmarks to be deleted.  After the delete process started, I moved the operating system's focus to a different window, and the bookmark library (and firefox) stopped responding.  
Then I selected 1200 bookmarks to delete.  The delete process never started;
the bookmark library and firefox stopped responding first.

Reproducible: Always

Steps to Reproduce:
1.Have a large number of bookmarks.  I had 3000+.
2.Select a large number to delete and begin the delete process, if possible.
3.Start another program, or click on an open window of another program.  
It doesn't matter whether you are connected to the internet or not.
Actual Results:  
The bookmark library and the main firefox program stop responding.

Expected Results:  
The bookmark library should have deleted the selected bookmarks, evidently one by one.
