Screenshot YouTube
Take a screenshot of any YouTube video with one click. Adds a “Screenshot” button to the YouTube video player which saves a screenshot of the currently playing video as a file, or copies it to the clipboard, or both. Optionally with keyboard shortcuts, and buttons for changing the playback rate. New in version 3.0.0: moved to the newly required manifest v3, and removed the history permission, which should also make the screenshot button more reliable. This extension does not contain any malicious or tracking code. No viruses. No ads. Only good software. Thanks to Ari Velazquez, and Zertsu for their contributions.
