awesome. Thank you so much. I used the following cmd's because simply using 'opera %s' overwrote the current tab instead of opening a new one which I prefer.
Code:
gconftool-2 --set /desktop/gnome/url-handlers/https/command -t string 'opera -newpage %s'
gconftool-2 --set /desktop/gnome/url-handlers/http/command -t string 'opera -newpage %s'
other possibilities are:
-newwindow--------open url in new window
-newpage----------open url in new page (tab)
-backgroundpage---open url in background page (tab)
-fullscreen---------start in full screen mode
and others for addressing specific tabs.
thanks again
cheers
