Move Firefox notification bar to bottom or add option to hide it

[WhiteKnight]

Current Situation

Currently, whenever I open Outlook Online, all of a sudden, a Firefox notification bar pops up at the top, requesting me to make Firefox the default e-mail handler for Outlook Online:

This is very much annoying, because it shifts down the currently displayed web content, so, when I’m clicking an item from my list, e.g., for deleting it, I regularly unintentionally hit the wrong item.

Desired Situation

Please, either add an option to hide that notification bar, or put it to the bottom of the page, so it won’t cause any more harm.
