Are you mad? It is unexpected for people coming from Windows or Mac, but as
soon as they understand it and get used to it, they love "copy on select" and
"paste with middle button" :)

And that is NOT the problem.

The problem is "go to copied link on middle click", which is complementing the paste action in firefox. Paste is fine, but going to a stored "url" by middle click is not always what is expected. it could be mitigated a little if the new url was opened as a new tab, but it does not - it replaces the existing page.
