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.
For awhile I was getting firefox crashes in Mint all the time. Turns out it was the snap version being unstable.
Why even enable snaps? It’s like asking to have headaches.
