[Bug 75758] Re: Firefox doesn't display new windows in new tabs despite option being set

[DarkMageZ]

something interesting for the debuggers. close firefox. move/delete
~/.mozilla/. launch firefox. goto about:config and watch the value of
this setting. go and toggle it from the menus.

what you will see:
when you first change the option from the menu. the value in about:config doesn't change.
change it back to how it originally was. notice how the value changes in about:config?

** Changed in: firefox (Ubuntu)
       Status: Needs Info => Confirmed
