Hi,

Wikipedia page says that FF 45.9.0 ESR will be End-of-Life on June 13th, 2017; though Mozilla release page says that it is the latest version offered on April 19, 2017.

Link to Wikipedia - https://en.wikipedia.org/wiki/Firefox_version_history#Firefox_45.9.0_ESR

Link to Mozilla - https://www.mozilla.org/en-US/firefox/45.9.0/releasenotes/

Further, Wikipedia mentions that FF 52.1.0 ESR is out on April 19, 2017 - https://en.wikipedia.org/wiki/Firefox_version_history#Firefox_52.1.0_ESR

So, which version is the latest one? And what's the EOL for that?

Thanks!

hi, currently we're in the phase where two esr versions are maintained at the same time - 45.9.0 is the last version that will be released in the 45esr branch. if there are still security issues cropping up till june it will receive a fix for them. after that date 52esr will be the only supported version.
