This extension is useful but please add these features: 1. Blur thumbnail instead of hiding option 2. Show the video duration while blurring thumbnail 3. On/off keyboard shortcut
Glad you're finding it useful and thank you for your feedback! To track suggestions 1 and 2 I've created https://github.com/domdomegg/hideytthumbnails-extension/issues/7 and suggestion 3 is tracked in https://github.com/domdomegg/hideytthumbnails-extension/issues/2
