Firefox Legacy
Firefox Legacy is an unofficial modified version of Mozilla Firefox that works on older Mac OS X versions, including 10.6 Snow Leopard, 10.7 Lion, and 10.8 Mountain Lion.
Download it now and breathe new life into your old Mac.
OS X 10.8 Mountain Lion
Current version for OS X 10.8 Mountain Lion: 71.0p2 (2020-09-15)
IMPORTANT NOTE ABOUT UPDATING TO v71: A new Firefox profile will be created when you update from earlier versions to version 71.0. To restore your previous data, type 'about:profiles' in the address bar, then find your previous profile (if you can't tell which, try each one) and set it as default. Then, restart Firefox Legacy. I apologize for the inconvenience; the cause of this issue is not known.
OS X 10.7 Lion
Current version for OS X 10.7 Lion: 68.12.0p3 (2021-01-24)
Now featuring support for numerous newer web standards, including Push, Service Workers, Feature Policy, ResizeObserver, Promise Rejection Events, more of the Animations API, and several CSS features. This should improve compatibility with many websites.
For security and privacy reasons, starting in version 68.12.0p3, support for TLS 1.0 and 1.1, HPKP, and the Battery API is disabled.

Only Firefox 52 is available for OS X 10.6 Snow Leopard; it will not be updated to a recent version due to technical limitations of the OS.
Note: the program is called 'Nightly' due to licensing restrictions prohibiting the use of the official Firefox branding.
