Thanks cor-el,

Your reply was informative.

So the latest active versions are; Firefox 69.0.1 Firefox 68.1.0esr and Firefox 60.9.0esr (superseded Firefox 52.9.0esr)

Is this correct ?

Regards pcbugfixer0

Yes, that should be correct at this moment.

There are also developer builds that are updated twice a week (Beta, Developer Edition) or twice a day (Nightly).

For now the Fx 60.9.0 ESR is a current version however the old 60 ESR branch will be EOL once Fx 70.0 and Fx 68.2.0 ESR are Released.
