Summary: when creating a new folder in the bookmark star dialogue, the editing of the new bookmark will close after three characters or if you add a space to the name. https://support.mozilla.org/en-US/questions/1134098#answer-904930 Steps to Reproduce: 1.

Eew. For me is seems to just cancel the name edit after a second or two, without regard to what's been typed. WFM in 47.0.1 and 48, broken in current Nightly (OS X).

It started for me in bets 49.1

AFAIK, if you are using sync, this is Bug 697649

I tried mozregression --good 2016-04-25 --bad 2016-08-01, ERROR: Build was expected to be bad! The initial good/bad range seems incorrect. Which is accurate as I cannot reproduce this with or without sync. "NI" me if I can test on a specific OS X or with other conditions.

Oops, looks like we dropped the ball here. I can still reproduce this with comment 0 on OS X, with my normal profile (with sync enabled). Dao, can you take a look at this? Seems likely to be a regression from the bookmark panel work we did a few releases ago?
