Serting Gnail to defaut mail handler, especially for mailto links

Hello everyone,

I am trying to get Gmail to be the Mailto handler for Qupzilla. After some sleuthing, I crafted the following URL:


This URL gives me a blank compose email within Gmail. The rreal fun happens when I click a mailto link.

The real problem is that Opera is opened! Yes, The Opera web browser opens when I click the mailto hyperlink–which explicitly calls out Qupzilla.

Any ideas?
