Details:

I've noticed multiple web pages not working properly in Firefox - there seems
to be some JavaScript inadvertently shown at the bottom of the page.

This is when using Firefox 68.0 for Ubuntu 18.04.
The JavaScript code does not show up when looking at these web pages using
Chromium.

Maybe the problem is that I don't let my Firefox reveal my location? I have an
extension called "Change Geolocation (location Guard)" installed.
Anyway, I don't think text like that should be shown just because my location
cannot be discerned.

Below is a copy of the text from bottom of the page
https://octave.sourceforge.io/. Similar text can e.g. be seen on these pages:

This is only a short abbreviated list of the changes that were introduced in
recent versions of Octave Forge. For a full list of changes please see the 
news archive.
{ const iframes = window.top.document.querySelectorAll("iframe[sandbox]"); for
(var i = 0; i < iframes.length; i++) { if (iframes[i].contentWindow) { if
(iframes[i].contentWindow.navigator) { if
(iframes[i].contentWindow.navigator.geolocation) { if
(navigator.geolocation.__proto__) { let cp =
iframes[i].contentWindow.navigator.geolocation.__proto__.getCurrentPosition;
if (cp !== navigator.geolocation.__proto__.getCurrentPosition) {
iframes[i].contentWindow.navigator.geolocation.__proto__.getCurrentPosition =
navigator.geolocation.__proto__.getCurrentPosition; } } } } } } }

And below is text from the  bottom of another page
(https://octave.sourceforge.io/parallel/index.html):

{ const iframes = window.top.document.querySelectorAll("iframe[sandbox]"); for
(var i = 0; i < iframes.length; i++) { if (iframes[i].contentWindow) { if
(iframes[i].contentWindow.navigator) { if
(iframes[i].contentWindow.navigator.geolocation) { if
(navigator.geolocation.__proto__) { let cp =
iframes[i].contentWindow.navigator.geolocation.__proto__.getCurrentPosition;
if (cp !== navigator.geolocation.__proto__.getCurrentPosition) {
iframes[i].contentWindow.navigator.geolocation.__proto__.getCurrentPosition =
navigator.geolocation.__proto__.getCurrentPosition; } } } } } } }{ const
iframes = window.top.document.querySelectorAll("iframe[sandbox]"); for (var i
= 0; i < iframes.length; i++) { if (iframes[i].contentWindow) { if
(iframes[i].contentWindow.navigator) { if
(iframes[i].contentWindow.navigator.geolocation) { if
(navigator.geolocation.__proto__) { let cp =
iframes[i].contentWindow.navigator.geolocation.__proto__.getCurrentPosition;
if (cp !== navigator.geolocation.__proto__.getCurrentPosition) {
iframes[i].contentWindow.navigator.geolocation.__proto__.getCurrentPosition =
navigator.geolocation.__proto__.getCurrentPosition; } } } } } } }
