Unfortunately, this breaks horribly if you're on a shitty network (for example I work a lot on the train) and/or slow hardware. The update check delays browser startup for more than a minute when connected to wifi with no internet (this happens a lot when going through rural areas) and the update after closing function has also burned me a few times when I closed the last window, then remembered I needed to check one last thing, but had to wait several minutes for the update to do its thing (a combination of old laptop, slow internet and many other things using resources).
