No WebExtension support, and unless Qt implements support for them, I'm not sure that'll change: https://github.com/qutebrowser/qutebrowser/issues/30
However, there's a built-in adblocker (which only blacklists hosts right now), and there are plans for something like uMatrix: https://github.com/qutebrowser/qutebrowser/issues/28
Actually on second thoughts extensions probably don't have a relationship with layout engine but with browser GUI so maybe no.
