Sometime ago I met Elementary OS and loved it, but it isn't stable yet.
Midori is the default browser of Elementary. If you go to "Applications" you can find and open Midori, but when you go to the Software Center you can't find it.
I want to delete Midori because I prefer Chromium, but as I can't find it in the Software Center, how I can remove it?
I don't know why you want remove Midori, but if you have this issue and really want remove Midori from your Elementary, you can follow these instructions:
Well done, your Midore browser was removed from Elementary!
