Firefox LegacyFirefox Legacy Firefox Legacy was an unofficial modified version of Mozilla Firefox that worked on older Mac OS X versions, including 10.6 Snow Leopard, 10.7 Lion, and 10.8 Mountain Lion. As of 2021-10-24, Firefox Legacy is no longer supported. It has become increasingly challenging to update it to a more modern Firefox version, and I no longer use it myself. It is no longer available for download
