Any way to disable "More tools..." collapsing feature?

Hello all. I know this is a more general question but this feature is driving me crazy. The URL and search bar take up so much space and yet there isn't room for a measly few icons on the location bar. To make it more clear, this is what I'm talking about. I want the addon icon to show up normally in the location bar - I don't need that much space for the URL and search bar. I think what frustrates me most is that it even collapses with even just one icon to the right of the search bar, even though the "More tools..." button is the same size.

Thank you.
