Since Canonical forces us to use the "snap" version of Firefox in the latest version of Ubuntu, I am using Firefox snap on an x86_64 and an aarch64 Ubuntu 23.04 machine.
The latest upgraded Firefox snap version,
- on my x86_64 machine is currently at 116.0.2-1 (snap Rev. 2987),
- while on my aarch64 machine is still at 115.0.2-1 (snap Rev. 2918).
This fact can also be verified at https://snapcraft.io/firefox.
Why?
