open facebook tab form in new browser tab

how to have form within FB open new tab?

thanks!

Since forms are added to a tab in Facebook, it is not possible to modify the form itself so that tab opens in a new browser tab.  However, you may want to check with Facebook help to see if there is an option to open tabs in a new browser tab when clicked.  I was unable to find an option to do so, but there may be one.
