I have briefly checked all your rapid games featuring the French (or something looking like a French), and guess what? There was no early ...Qb6 in any one of them. And none of them was an advance French, as some posters here were assuming.
Anyway, I think that while your main concern should be the numerous tactical oversights you make in the game, to apply something simple, clear-cut and not so theoretical. Take for example the rather rare 3.Bd3 variation- I think the following video presents all you have to know abut it (or even, more than you could need right now).
The French is a very strong opening for black. It's extremely aggressive so many people play variations like the Advance or the Exchange. To win you have to know the lines better than your opponent and be a better player.
