If grew that much in a short amount of time then it sounds like it's not receiving enough light. This will cause the new growth to be weak and spindly resulting in it falling over. You might want to consider in either cutting half of the new growth off and supporting it or just supporting the whole thing by using some stakes and some twist ties loosely on the branches. The tree needs to be moved somewhere to get enough sunlight. If that's notossible then you can use some grow lights. Hope that helps you.
Good luck!

I think cutting each branch about 1/3 to 1/2 off will help in supporting itslef as well as branching out of new shoots. Then pinch the summer growth on all branches after every 6th leaf on each new branch. This pinching practice helps formation of fig embryos than elongation of the branches.
