Oh great, now I’ve updated Firefox on the phone it won’t open anymore. And people wonder why I usually have lots of apps that haven’t been updated. Then there are the operating systems that I’ve chosen to not update as well. To be fair, running an older OS might conceivably cause issues. But if a given app version officially supports a particular OS version why should there be a problem? No, the real problem is that controlling Apple won’t let you uninstall or roll back software. The fatherless children that they are!
