Is it possible to customize the file save dialog in google chrome?

Question

Google Chrome

I am a longtime supporter of firefox, but after the next update, the usual things stopped working, so I decided to try the most common competitor. So far, I like it more than not, but there are a couple of annoying things:
1) In the fox, when downloading files, there was a dialog where you could choose to save the file or open it in some program. Chrome only saves. Opening certain file types is configurable, but it's not even close. Is it possible somehow to make the download dialog like firefox?
2) I am a fan of opening a million tabs. Accordingly, over time they become so small that it is difficult to find the right one. Yes, and when you restart the browser all at once open again! I want it like a fox! Can you suggest a way?

Stay on the fox.
