Everyone has their own browser preferences, but in the interest of saving you time and heartache (particularly if you're creating a 9 or 10 generation chart!) we strongly recommend you use Google Chrome when using the Family Tree Prints family tree maker app. Why you might ask?
The short answer is because our family tree maker is optimized for Google Chrome, that's where you'll have the best experience. Google Chrome requires your physical computer to do less of the actual processing work, which means it's faster and more reliable. This is particularly important the more generations you'd like displayed in your final pedigree chart. For example, if you're creating a 10 generation pedigree chart using Firefox, unless your computer is a beast, the chart may simply be too large to be processed for final download (real, sad, true story right there folks!). If you create the same 10 generation pedigree chart using Google Chrome, the family tree generator can handle it like a champ and have you chart processed in a matter of minutes.
Don't have Google Chrome installed on your computer? Don't worry, it's easy and you can take care of that here.
