As of this morning I upgraded my Firefox to version 15.0. Or well, it did it for me. That's when my issue began.

I've configured Firefox so that when I open up a new tab via Ctrl-T that it loads the about:newtab page which was released in version 14.x(?). I use this functionality extensively. I visit a page from the about:newtab page, read it, press the back button and pick another frequent website from the display I want to visit.

However as of v15.0 the latter part is no longer functioning, after visiting a website from the about:newtab page the back button will not let me go back to the about:newtab page. Firefox acts as if that history entry was never there.

I've tried searching the release notes to see if this change was intentional or a reported bug, but I have not found anything related so far.

Is there anyway to (re)configure the new Firefox v15.0 to let me access the about:newtab page via a tab's history?

EDIT:

It appears that this only affects the initial 'visit' to the about:newtab page when opening a new tab, manually visiting about:newtab will register it as a history entry and allow it to be navigated to via the back and forward buttons.

So I guess this changes my question to 'How can I make Firefox 15.0 treat the inital page from a newtab as a history entry'.
