It seems like it’s doing the expected and logical action then: it yells at you when you come back to the system but if it can’t update itself it sends you to the manual download. This seems completely reasonable. It doesn’t really matter why the browsers can’t auto-update with too large of a delta, that’s a concern to the authors of the software. If you really want to solve this I would write some kind of update script that runs on startup of your computer or manage your browser installations with a package manager. Or you could use a browser like Safari on Mac where the OS software updates manage the browser.
