Default is to automatically update, but can only happen when you're running as root (or administrator in other OS).
It was running under root since I'm doing upgrades to the master machine for an upcoming convention.
I even forced a Help/Check for updates. It always (including just now) said there were none.
Our Firefox is set to check, but ask before installing anything, but I never saw any indication updates were available. In the past, nag popups happened fairly quickly after a new release.
I can always do a manual update, or wait for the VL packaged releases, but was more curious as to why the VL version was ignoring checks for new releases in case the install of 22.214.171.124 changed something, or left some cruft behind someplace that borked it that I need to clean up.
I will stick the one Exeterdad's working on in once it's available and see how it does.
