Copy Frame for Chrome and Firefox
Copy Frame is an extension for Chrome and Firefox that lets you copy the current frame of a video from the context menu directly to your clipboard. It's a convenient tool to get clean screenshots from videos without having to crop a screenshot of your browser window or entire desktop, or having to resize your browser to make sure the video element is displayed at the video's native resolution.
You can also copy a frame to your clipboard in a number of different ways. The first way is by opening the context menu on a video and clicking the "Copy frame" option. The second way is by right-clicking a video element and choosing "Copy frame". The third way is by using the keyboard shortcut CTRL+SHIFT+C.
