directly from the browser's address bar. The execution of these one-line
scripts has affects only on the website's loaded document.
The advantage with this approach; is that it uses vanilla Javascript and doesn't require any plugin on the browser or needs the developer console. You just need to copy/past the code into the address bar, after the prefix "Javascript:" typed beforehand.
Important : Don't copy/past the code with the prefix "javascript:" at once, otherwise the browser will ignore the prefix when pasting in the address bar.
