We should also evaluate whether availability in the Mac App Store is important for adoption, if Apple ends up making that the default way to get software on the Mac. Note that there is already a feature page tracking the Mac App store integration. Those who in 2019 still run a Mac that is stuck with OS X 10.7.5 Lion because of hardware limitations can still use Waterfox version 56.2.10 from May 2019. It's based on Firefox but stripped off of some technologies. Waterfox is compatible with Firefox syncing of bookmarks, tabs, etc. Over devices (mobiles).
Firefox For Mac 10.7.5
- On August 2, 2016, Firefox 48.0 was released. It is scheduled to be replaced by Firefox 49.0 on September 13, 2016. At that point, Mac users using OS X 10.6 Snow Leopard, 10.7 Lion, and 10.8 Mountain Lion will be left behind by the current versions of Firefox. It will be a sad day, as Firefox is the last major browser to support Mac OS X 10.6.
