The above mentioned install seems to install 2 versions of browsers.
1) Minefield - Titled Minefield
2) Fennec - titled Firefox

Minefield looks like the full featured Firefox browser with sidebars etc and with no kinetic scrolling

Fennec is the mobile version with kinetic scrolling.

Is there a way I can only install Fennec - so as to limit the memory used up in installed 2 apps ?
