I recently switched one of my laptops over from OpenBSD i386 to amd64, which meant reinstalling all packages. Due to using an older mirror, this ended up downgrading a number of packages, among them a certain browser which displays a helpful message telling me I’m “up to date” whenever the currently running version differs from the previous run version.

Yes, you’re reading that right. I went from version 18 to version 17. And somebody decided that was an upgrade. The silly part is you can go to the magic URL and get the same page in any version of Firefox, but if you use another browser like Chrome they sniff the user agent and redirect you elsewhere. Why isn’t the “not Firefox” check a “not up to date Firefox” check?
