Firefox ESR 60.6.2+ still unavailable for me

[Guilherme Vieira <super.driver.512@gmail.com>]

Hi folks!

I've been waiting for a few days now for a Firefox ESR update that fixes the infamous add-ons certificates issue, but still nothing:

• Debian version: Stretch.
• Arch: amd64.
• firefox-esr version: 60.6.1esr-1~deb9u1

I just ran:

$ sudo apt update
[sudo] password for gui:

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

But as you can see there's still no update for firefox-esr, which is still at version 60.6.1:

$ apt show firefox-esr
Package: firefox-esr
Version: 60.6.1esr-1~deb9u1

This is my sources.list:

# stretch-updates, previously known as 'volatile'

deb [arch=amd64] https://download.docker.com/linux/debian stretch stable
# deb-src [arch=amd64] https://download.docker.com/linux/debian stretch stable

I live in Brazil, so those sources are probably redirecting me to a geologically closer mirror.

What should I do in order to have Firefox ESR updated to the latest version?
