Each lash will have an assignment by heart different that it will consume more memory, but will have better compatibility. This compatibility comes related with which each lash will work as if of a window more it was, with all the extras that we want in certain lash, like bars of tools.
The clicks carried out with the button of the means of the mouse or with the key Control they will open the connections in a new lash and we will be able to navigate among these through the keyboard.
Those pop-ups that they do not have to show the address and other basic functions will open up in a new window, while those that do not specify anything special they will open up in a new lash.
