Comment 5 for bug 110571

- no add-ons
- default theme only
- German and English (GB) language packs 2.0

HOWTO:
1. start Firefox
2. open the bookmark manager
3. select 5 bookmarks with shift and cursor up/down keys
4. press delete key
5. bookmark manager still shows the deleted bookmarks
6. jump to another bookmark folder
7. jump back to the folder where you have deleted the 5 bookmarks
8. deleted bookmarks are gone

BTW the bug does not appear always, but very often.
