Almost the best extension possible (for it's purposes). Please, consider adding an ability to save gif AND turn youtube frames to a link (which is showing instead of youtube frame). Anyway, thank You very much for such nice peace of software!)
Thank you for the review. Saving GIFs should be okay. For example, the GIF of the demo on https://github.com/gildas-lormeau/SingleFile can be saved without any particular issue. Replacing frames with a link to their URL is an interesting idea. If you want to discuss it, don't hesitate to contact me by email or on Github.
