Can you give me a specific example of where this does not happen, and which browser you're using? This works by default for me in Safari, here's a screenshot:

I generally dislike those javasripts that prevent me from leaving, a bit nanny-state-ish. I think it's great we auto-save instead.

Yeah, the one in the shot above is a browser native thing. I thought they all did it now but maybe they don't or we're accidentally disabling it, or the text in question was being typed into some unusual field.

@chad - the autosave functionality is fantastic. I think this compensates for the close tab issue, except for the corner cases of when the AJAX request to remarkup is still pending.

My internet connection is comparatively slow so I guess it's a slight issue for me, but shouldn't be a problem for most others. On a related note, I experimented a bit with the auto save and I found another minor possible bug in T4580

(Looks like Safari is the only one that does this by default.)

◀ Merged tasks: T4668.

T4668 is a special case of this. If we do implement a navigation warning, it should also check for active uploads.

After we've been using phabricator for a while, we found the auto-save is a better approach to handling closing-browsers. We've had people who've started writing a comment and then changed their mind half way, and appreciated not getting a "are you sure you want to quit" nagging dialog.
