I used the search option in the free version of "Family Tree Builder" When I start this program, a new window of Mozilla Firefox also opens. Do you think the problem is that the program is connected to Firefox and not Explorer?
Thank you for the answer. I am very sorry for the late response.
An option "Smart Research" in Family Tree Builder is the Premium feature only - so to use it your program required Premium verson. Please note that in case you will buy Premium for Family Tree Builder - you will get the Premium option forever for our Family Tree Builder software.
PS. Smart Research can be done using IE only - nor Firefox or another browser.
