After creating a fresh installation of Ubuntu 24.04, I installed DEB Firefox from APT by following Mozilla’s instructions from here. But I noticed that it was secretly replaced with Snap Firefox. I was able to verify this by checking the About Firefox page. This is the third time I noticed this.
There is RedHat and SUSE. Which are also the only two certified distros for running corporate/enterprise CAD/CAM/FEA and PLM software. They both provide rock solid stability.
