I have been trying out several newcomer browsers (using webkit) as alternatives to Firefox, which seems increasingly slow to me.

Midori and Arora both allow the back button of my mouse to work, as does Firefox.

However, Epiphany, which would be my first choice, does not, and I can't find any way whatsoever of configuring it to do so.

Can anyone please shed some light on this, and perhaps suggest a simple fix?

I can't see why such a 'flagship' app should lack such an essential feature.
