Copy Relative URL v1.0
This very simple extension adds a "Copy Relative URL" item to the context menu when you right click a link. So, for instance, if you right click a link and the URL is https://dev.example.com/some-path/?q=1#hash, it will copy /some-path/?q=1#hash to your clipboard so you can paste that nice, clean relative link in your code.
A niche use case! But I'm a web developer and I have to do that a lot more than most so I wrote an extension to make it faster.
