Yes I am on Firefox also but yes I can see what you mean not aligned
I would Check your Layer parallax settings.
The layer that has the Text on it...you may of accidentally or intentionally set it to appear that way.. You would have layer parallax visible in editor turned off and so it appears normal but when you run the game it appears at it true parallax position...
its easy to do because the layer parallax settings are located right under the layer dimensions ...you can easily set this of slightly and not notice..especially if "Parallax visible in Editor" is turned off
its a good habit to always turn this on so you can position objects on layers properly
Hope it helps
