3 of my bookmarks are configured to open in sidebar.

#1: http://www.spiegel.de/dienste/sidebar
#2: http://www.heise.de/newsticker/sidebar1.html
#3: http://dict.tu-chemnitz.de/?mini=1

Sometimes I can't switch between these bookmarks anymore.

Example: 

#1 is opened in sidebar, 
I click on #2 and nothing happens, same for #3. 
Closing the sidebar doesn't fix the problem. 
For example, I close the sidebar, and click on #2 to open it again. 
Sidebar opens as expected but not with #2 but with the one that was opened before I closed the sidebar.

I always have to restart the browser to get it working again. Also I can't remember I had this bug in alpha builds.

Reproducible: Sometimes
