With your mouse, go to the beginning of the line of text you wish to copy and press the left mouse button. Keep the left mouse button held and drag your mouse across the rest of the text you wish to copy. (It'll start getting highlighted) Let go when you get to the end of the text you wish to copy. Then in your browser click Edit from along the top, then copy.

Then go into the place you want to paste your copied item (if it's a web link, then the address bar at the top of the browser) and put your cursor into that as if you're going to type some text. Then go into Edit and click paste. That'll paste the copied text into the browser.
