1. Open about:preferences in a new tab, close other tabs and other FF windows
2. Open url   data:,a   in a new selected tab. Navigate to   data:,b
3. Open task manager, focus child FF process, press Delete

AR:  Back button in urlar is disabled
ER:  Back button in urlar should be enabled

 Current Firefox UI leaves me no option but to restore tab.
 I don't want to restore that exact history item that crashed the tab, and this is logical.
