On FF latest (and always) I have been able to open a whole bookmark folder
as tabs by middle-click.
In the FF portable I am using on a USB drive this does not happen, I have
to right-click on the bookmarks-drop-down and choose 'Open all in tabs'.
Is this how it should be, or is there a setting that I have long forgotten?
I do use TabMixPlus, but not sure that should make a difference.
