My question pretty much says it all.

I constantly get a message saying my firefox is "critically outdated." But when I try to download the latest version, message says I need a newer OS. But I CAN'T get a newer OS.

I have MacOS 10.8.5. Is there a newer version of mozilla I can use? I have 48.0.2.

So what are my options?

Firefox 49.0 and later has required Mac OSX 10.9+

The Fx 45.9.0esr is actually much more updated security wise compared to the older Fx 48.0.2.


Firefox support has ended for Mac OS X 10.6, 10.7 and 10.8 https://support.mozilla.org/en-US/kb/firefox-osx
