Shift + Click to select a range of text

Previously on MacOS, to select a long excerpt in a long body of text, I would: 1. Select the beginning of text I want to select (e.g., double-click the first word). 2. Go to the end of the text I want to select (e.g., scroll down a few pages). 3. Press "Shift" and click where I want selection to end. – This was working and I used this all the time for copy-pasting text. But recently (1-2 years ago?) it stopped working. At least in Chrome (still works in Notes though). Questions: 1. Can I re-enable my old way of selecting text? 1. Is there an equally fast way of selecting and copying a few pages of text?
