>>> My Info: Win7_64, Nightly 53, 32bit, ID 20161119030204 (2016-11-19) STR_1: 1. Open url [1] 2. Execute code [2] in scratchpad or web console 3. Click on "Link1" 4. Pause the opened video, click in the center of timeline 5. Press Ctrl+Right, then (not necessary) immediately stop the video AR: New video starts from ~5% from the start ER: New video should start from the very beginning STR_2: (difference in Step 1) 1. Open local folder with at least 2 long videos (probably even 1 video is enough) 2. Execute code [2] in scratchpad or web console 3. Click on "Link1" 4. Pause the opened video, click in the center of timeline 5. Press Ctrl+Right, then (not necessary) immediately stop the video Notes: 1) I wrote that script several years ago, only remember that it replaces "src" of video on Ctrl+Right 2) In case of long videos 5% from the start is several minutes, so it's quite noticeable This is regression from bug 1274520.
