I am a longtime subscriber to Ancestry.com. I have used its Member Tree program online primarily for family history research and family tree compilation. Alternately, I have used Firefox and Safari (both Mac versions) to conduct my research with Ancestry.com's vast search archives. Before I will explain why Ancestry won't support Safari (for Mac or Windows), I will explain this: I find using Safari on Ancestry.com to be much faster than Firefox (webpage refresh, graphical content loading, editing data, accessing to search archives). When I used Firefox, I founded that it's slow and bit cumbersome, especially page refreshing and loading of content after editing data or accessing to search archives. On Safari, page refreshing (command-r) and content loading to completion lasted about 2 to 3 seconds; on Firefox, it varies from 3 to 5 seconds. I'm on 2 MBps Internet speed (it's all I can afford under my ISP plan) under Mac OS X.4.11, PPC-based G4. However, the biggest frequent and annoying issue I have with Ancestry.com while using Safari is "bad server response". At times, I had Firefox and Safari running at the same time, comparing them while using Ancestry.com. Under Firefox (ver 3.6.3), using Ancestry.com's search archives or editing a person's data generates no "bad server response". Under Safari, the "bad server response" pops up almost every time whether editing a person's data, switching to another person or accessing search archives. The command message is this: This kind of problem forced me to click "command-r" several times to force a server response and usually it works. At one point, I had to "com-r" about 50 times and finally got a result! Reporting bug message to Apple several times produced no results for me. I don't know why Apple won't reply back to me (I gave them my email address) on this issue. It appears that Apple won't fix or solve this issue with Ancestry.com. Few times, I sent messages to Ancestry.com asking for assistance to deal or fix this issue. They responded back to me the usual message: While I have no problem using Firefox on Ancestry.com, I still founded it to be slow and bit cumbersome to use anyway. I would rather work with Safari on Ancestry.com because time is of essence for me (for accessing on the fly). I had encouraged Ancestry.com tech people to consider make the site compatible to Safari, considering that maybe more Ancestry subscribers are using Macs or using Safari for Windows (I don't know the exact numbers of how many subscribers using Mac or Win). I'm worried about Ancestry.com could try to make its website completely compatible with only strictly Microsoft Internet Explorer or Firefox, leaving out Safari. It's similar to OneGreatFamily.com (they won't support Mac or make compatible for Safari). Has any Mac subscriber encounter this "bad server response" issue while using Safari on Ancestry.com? I don't know if this is a web engine issue or programming problem (I'm not familiar with the more technical details of the browser's engine and codes). It's kind of ironic that Ancestry is working on FamilyTreeMaker for Mac soon. Any comment or insight is appreciated. Please do NOT ask or tell me to cancel subscription. All I wanted from Ancestry.com is to change its attitude regarding Safari and try to work on a positive level with current and potential Mac subscribers to Ancestry.com.
