Can you give me more information on how this can be best resolved if there is a way?
Only the developer can solve this problem. You can avoid this problem if you don't allow one browser to take up more than 3-4gb of RAM (Removing unnecessary or used elements on the page).

This code contains an event handler. It should be added to the page before it is downloaded (preferably). Use "Browser -> execute every time the page loads". From "Tools -> execute the code" access to the root object "windows" is not. From this error there is - no "windows.document"
