middle mouse button opens tabs in foreground

[Treap]

clicking with middle mouse button on links started to open them in new tab in foreground instead of background.
why is that? and is that possible to change? i can't see option like that in settings
edit: ah, nevermind, I must've change my mouse buttons layout somehow :v

@Treap Shift+Middle-click would do that. There is no setting to change the behaviour. Middle-click opens tabs in the background.
