CopyURL von lytoooo0

If users want to copy the current URL without using mouse, probably the only way is pressing <C-l> and then <C-c>, after which the search bar is keeling focused and selected. As a Vimium user nothing could be more annoying. Thus I created this simple add-on which provides a floating button whose only function is writing the URL to clipboard after being clicked. It works well with hint-link functions provided by Vimium-like extension.
