User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040804 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040804 This occurs, when a link is copied and pasted into a Mozilla browser window: If the link contains two or more lines, the line breaks are parsed away and the link is handled like it was in one line, so like having recieved a link in an email which was broken in 2 line (thanks, ms outlook). But instead of showing the whole link taken without line breaks, just the first line is shown in the url address line in mozilla. E.g.: action: paste "http://www .mozilla.org/" into a browsing window. effect: the mozilla.org site is shown, but in the address line just "http://www" shows up. if you do it in a tabbed window, and change from the paste-tab to another and change back, the whole paste-string without line breaks is shown. This could be used to get the user to copy links with line breaks into a browser window, and get the user to surf a fake web-site which has the same sub-domain as a known one. then just the sub-domain is shown to the user. Reproducible: Always Steps to Reproduce: 1. copy link with line breaks e.g. "http://www .mozilla.org/" 2. paste it into mozilla browser window Actual Results: an incomplete url string is shown to the user Expected Results: show the complete url which is used to retrieve to web site which is shown to the user

to my knowledge this behaviour applies to at least mozilla 1.7.2 and 1.7.3 /linux, not to firefox 1.0. I couldn't see it under windows at all.
