Hmm, that's weird. I tried on a half dozen computers with macOS, ubuntu, and Windows with the same result. Did you try using the linked jsfiddle or some other code?

lol what???
How is this closed? I encountered the same issue, whenever I set data fields to something that casts to false, it becomes undefined.

It looks like to be a problem of Firefox's devtools and unrelated to Vue. https://jsfiddle.net/09jzhm6o/

Hello, Firefox Console owner here. This is indeed a Firefox Console issue when evaluating a getter that returns false, "" or 0.
I'm working on a fix and will keep you updated. Thanks a lot for the report.
