Can you place share how you find a Tom's Hardware AMP page? I work at Mozilla and would like to test this. Google Search in Firefox for Android just returns regular www URLs. If I manually change "www." to "amp." (reversing your fix), I get a 404 page, not an AMP article.
Edit: I copied an AMP URL (https://www.google.com/amp/s/amp.tomshardware.com/...) from Google search in Chrome. I posted email it into Firefox and it redirected to a www. page on tomshardware.com that loaded successfully.
