Bottom slide cursor do not cover the whole picture: I have instead to enlarge the frame
I am working on a MacBook Pro (old model of 2009) with OS X El Capitan 10.11.6 and Firefox Quantum 67.0.4. Some URL have a wider picture which goes outside my window, and then a bottom slide cursor appears. But with the cursor I cannot view the whole page, and I have to enlarge my window's frame to see the right part of the web page I am looking. Am I doing something wrong??
