Created attachment 8902254 [details] long_url.json navigating to a long url by clicking on it in the JSON viewer does not work. steps to reproduce: 1. ensure devtools.jsonview.enabled is true 2. navigate to a json document containing a long url (eg. the attached file) 3. click on the url expected result: either the url should change to an input/text field so it can be copied, or the browser navigates to that url actual result: browser navigates to a malformed url - in the attachment i have http://www.glob.com.au.s3-website-us-east-1.amazonaws.com/ the json viewer initially shows this as a complete url, however after clicking on it, but before navigation, this changes to http://www.glob.com.au.s…s-east-1.amazonaws.com/, which is the url the browser tries to visit - http://www.glob.com.au.xn--ss-east-1-g674c.amazonaws.com/
oh, this is with the latest nightly - 57.0a1 (2017-08-29) (64-bit), on osx.
