The Download YouTube Videos extension no longer seems to work. I think this is a result of a change done at YouTube and not something in either SeaMonkey or the extension. The Web page in addons.mozilla.org indicates the developer has removed the extension.
There is a work-around using Video LAN (VLC) from <http://www.videolan.org/>. 1. I start a YouTube video in SeaMonkey, copy the URI, and stop the YouTube stream. 2. After launching VLC, I select [Media > Open Network Stream] on its menu bar. 3. I select the Play button on the Open Media window and VERY QUICKLY select the red Record button on the main VLC window. 4. [The following applies to Windows' [Libraries > Videos], where VLC writes the recorded file. Similar methods should exist in other systems.] a. On the VLC menu bar, I select [Media > Convert/Save], the resulting File tab, and the +Add button. b. Navigating to [Libraries > Videos] in the file-selection window, I select the recorded file and select Convert from the pull-down menu from the Convert/Save button using the down-pointing triangle. c. On the Convert window, I select the "Video - H.264 + MP3 (MP4)" profile, navigate to where I really want to save the converted stream file, enter my preferred file-name, and select the Start button. 5. After checking that VLC can indeed play the converted file, I delete the original recorded file. -- David E. Ross <http://www.rossde.com/> President Trump: Please stop using Twitter.
