User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1 Build Identifier: Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1 In version 3.n firefox the DownloadHelper plugin could save videos (i.e., anything on youtube or other sites) that had already been downloaded (or continue saving partially partially downloaded videos) from the cache. In version 4, DownloadHelper restarts video downloads from the beginning even if they have been completely or partially downloaded. This may apply to any type of download (I only use downloadhelp for videos) but probably is most noticeable on audio and video files where folks watch or listen to all or part of a video or audio file before deciding to click on the DownloadHelper link to save it. Possibly related to the conundrums that cause firefox 4 to take forever to clear the cache (I was clearing my cache in a attempt to get firefox to recognize a new favicon.ico image I had uploaded to a website...) Reproducible: Always Steps to Reproduce: 1. Start watching youtube video 2. Use DownloadHelper to save video after it is partially or completely downloaded. 3. Actual Results: DownloadHelper will start a new download immediatley Expected Results: DownloadHelper should save the video from the cache if it already completely downloaded, or wait till the download is complete and then save it, or continue and complete the download if the youtube page is closed before the download is complete (which is how DownloadHelper use to work in version 3.n, much preferable for anyone with a slow connection)
