Downloads bar showed up on my work pc, just for one profile, how to go back to downloads that show up on the bottom of the screen?
You could try chrome://flags/ > Disable Download Bubble, but if the devs. decide this is going to be permanent, they often remove options from chrome://flags/.

getting rid of that download toolbar would be great.
