User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1 Build ID: 20110928134238 Steps to reproduce: Steps to reproduce: 1: Go to about:config. 2: Make sure that the setting browser.urlbar.trimURLs is set to true (so that http:// isn't shown in the Firefox location bar). 3: Go to any http:// page containing a text area (say, the "post a reply" section on this page when logged in). 4: Double-click on the URL in the Firefox location bar so that the complete URL is selected. 5: While pointing at the URL in the location bar, press down the left mouse button. 6: Move the mouse cursor to the "post a reply" text area. 7: Release the left mouse button. Actual results: The URL is now pasted into the text area without the leading http:// part. Expected results: If browser.urlbar.trimURLs is set to false, the complete URL (including http://) is pasted into the text area. SeaMonkey always seems to display the http:// part (no browser.urlbar.trimURLs appears in my about:config) and so is unaffected by this bug.

Just some clarification: the text seems to be a copy of some text I wrote on the Mozillazine forums, and some of the wordings (e.g. "this page") may look a bit confusing if read out of context. I didn't report any bug myself since it looked like a dupe of bug 670587 (which is about dragging and dropping into text areas in external programs).

A patch for bug 670587 would fix this - the drag and drop *target* is mostly irrelevant.
