User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release) Build ID: 20140506152807 Steps to reproduce: Insert a multi-line buffer into the URL bar Actual results: Spaces replace newlines in the buffer, making the URL invalid Expected results: Newlines should simply be eliminated when pasting text into the URL bar, as occurred in prior versions of Firefox. The major use-case in support of this behavior is an attempt to copy and paste a URL from a program like PuTTY, or other terminal emulator, from text that has wrapped in the terminal. If the newlines are eliminated, the URL can load without further editing. If spaces are inserted, which is never the right behavior because properly formed URLs should have spaces, then the URL must be edited manually. I note a recent bug report (321000) requesting opposite behavior in the "search bar." Replacing newlines with spaces may well be appropriate there, but the URL bar has a different role, and different behavior is appropriate for it.
I reproduced in Fx29, but not reproduce in Fx30, fixed?
