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.
Not defending Ubuntu but wasn’t this clarified to be Mozilla’s deploying it via Snap and requesting to remove the apt installation?
