A particlar website doesn't display correctly on THIS PC only
I am currently looking at LLBean website (see picture below). There is a problem on this machine, quite readily apparent. ONLY on this machine, in Firefox! My other PC is fine, I left the site open for 4 hours to check, looks as it should. Please help me understand what could POSSIBLY cause this on just one PC, only in this browser, which I tried uninstall, clear all the data, reinstall to no avail.

This is usually caused by a problem with a specific font and you need to identify this font and fix this.
Note that you shouldn't disable "Allow pages to choose their own fonts, instead of your selections above" as this will cause issues with iconic fonts used by webpages to display small icons (you may see text labels instead of icons).
You can right-click and select "Inspect" to open the built-in Inspector with this element selected.
You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Fonts tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.
