I am running Firefox version 52.0.2 (32-bit) on a Raspberry Pi and it is complaining that it is critically out of date.
Also GitHub says it won't run correctlyon this version.
This was installed as part of the AstroPi3 installation and this recommended fixing to this version of FF.
Is this advice now out of date and is there a more up to date version of FF that works better?

Chris

Chris,

What operating system is it running?

Paul

Linux Mate version 4.4.38-v7+ armv7l

Chris,

I have stopped running Ubuntu Mate and now use Raspbian so I am a little out of date.
There was an issue which stopped Firefox running and the fix was to downgrade Firefox and to stop automatic updates.
From what I can see via internet searching the issue has been resolved so I assume you would need to turn on automatic updates again.
I cannot recall how to do this but a search should provide an answer.
Paul

Can you do this please and provide the output:
cat /etc/lsb-release

In my case I get
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"

My firefox version is
$> dpkg -l firefox

I am afraid that if you want to have a newer version of Firefox that you’ll need to upgrade to Ubuntu Mate 18.04.

I am running on a Raspberry Pi 3 and from what I can see Mate 18.04 is not available. It's coming Real Soon Now I hear.

There is no install medium for Ubuntu 18.04 for RPi but you can upgrade to it with the proper Ubuntu tools. I have it running on my RPis since several months now and it works great.
