I recently installed the new Facebook Container addon. I keep the Facebook tab open and pinned.
If I run a search or enter a new URL in the location bar and Facebook is the active tab, the FB tab is closed. The search or new page is still shown in a new tab.
I've also got Tree style Tab installed in case that is relevant.
If another tab is active (i.e. not the FB one), then it still seems to work correctly.
