Beginning February 1, 2018, the entire FamilySearch.org website will no longer be supporting Microsoft's Internet Explorer, including Internet Explorer 11 and all previous versions. Those continuing to use the Internet Explorer browser program will begin to experience bugs. FamilySearch will not be fixing those Internet Explorer bugs. Users of the FamilySearch.org website are being encouraged to use Edge, Chrome, Firefox or Safari.
I recently wrote about the issues accompanying continued use of the old Personal Ancestral File program. This is another example of how software continues to change and, in some cases, abandoned by its developers. Microsoft discontinued support of the Internet Explorer back on January 12, 2016. Quoting from a Wikipedia article on Internet Explorer:
On March 17, 2015, Microsoft announced that Microsoft Edge would replace Internet Explorer as the default browser on its Windows 10 devices. This effectively makes Internet Explorer 11 the last release. Internet Explorer, however, remains on Windows 10 primarily for enterprise purposes. Starting January 12, 2016, only Internet Explorer 11 is supported. Support varies based on the operating system's technical capabilities and its support lifecycle.I left in the links and footnotes for further information. I would guess that many genealogists are still using Internet Explorer. Some of them are probably experiencing problems with their internet activities and I would assume that some of them do not realize that the problem is with their continued use of Internet Explorer.
