User Agent: Mozilla/5.0 (Windows NT 6.0; rv:15.0) Gecko/20100101 Firefox/15.0 Build ID: 20120824154833 Steps to reproduce: I have downloaded a video file from a website. After 95% of the video was downloaded, firefox download manager stopped the download and indicated "failed" (maybe due to bad internet connection or a problem at the website server). At that point 95% of the video was already downloaded. Actual results: In Firefox download-manager I double-clicked the line with the video name. I expected the file that was downloaded (95% or the original file) to open. However, instead of opening the video file, firefox deleted to video file and started to download it again. Expected results: When double clicking the download manager, firefox should never delete files, unless the user confirms it. Also using double-click to restart a download is a bad idea. The "restart download icon" should be active and be used for that purpose.

Why was this bug marked as duplicate of bug 87151 ??? The other bug is an entirely different aspect of the download manager!
