Hero Thumb Downloader

First time trying this edge extension.. tapped the ` key (above Tab) on a video playing on YouTube , and although it did open a new tab, the image was of a very small and broken thumbnail. Upped to 5 stars.. tried a different video and it worked perfectly. Thank you! This will save me a lot of time. Only improvement I can think of would be a batch downloading option like from a playlist or the Videos part, showing all videos on a channel. Also I appreciate privacy only needing access to youtube urls. ⭐⭐⭐⭐⭐
