This is related to `trackingprotection` breakage #1101005

Looking at the devtools console, here are the blocked resources:

The resource at “https://ssl.google-analytics.com/ga.js” was blocked because content blocking is enabled.[Learn More] www.scottishpower.co.uk
The resource at “https://www.googletagmanager.com/gtm.js?id=GTM-TVPX69” was blocked because content blocking is enabled.[Learn More] www.scottishpower.co.uk

So these are the domains to test:
ssl.google-analytics.com
www.googletagmanager.com

I opened the URL in a fresh browser profile (Firefox Nightly 63, uMatrix installed, normal mode) and loaded the page. The Help sections did not load.

I disabled the Spoof Referrer option in uMatrix and then *WHITELISTED*:
-ssl.google-analytics.com

After this, theHelp sections became accessible.
The other resources didn't help.

ssl.google-analytics.com can be found in the disconnect-blacklist.json, disconnect-entitylist.json and disconnect_mapping.py.

So in conclusion:
google-analytics.com - Analytics = [tp-analytics]

Indeed, the links work if I allow https://ssl.google-analytics.com/ga.js in strict mode. And if I shim that script so that it defines window._gaq = {}, then the links begin working.

The issue is not longer reproducible, regardless if ETP is Strict or Standard. Now all options are functional redirecting to the corresponding page.

Tested with:
Browser / Version: Firefox Nightly 86.0a1 (2021-01-18)
Operating System: Windows 10 Pro

Indeed, the links work if I allow https://ssl.google-analytics.com/ga.js in strict mode. And if I shim that script so that it defines window._gaq = {}, then the links begin working.

Shim was added in bug 1637329 and enabled in bug 1693386 for Firefox 87.
