It's because we block rebuyengine.com as a tracker.

The site now has a banner up, suggesting to disable ETP or switch browsers. @tim, do you think we can unblock this page? I'm happy to reach out to them afterwards.

If you’re using Firefox with Enhanced Tracking Protection, certain features may be blocked. Please disable strict tracking settings or switch browsers for the best experience.

There is nothing we can unblock. I tested the site with ETP disabled, and the banner is still displayed. I think the website detects Firefox user agents and shows the banner. The website loads fine even in ETP strict mode if I spoof the user agent to Chrome.

We might be able to deploy a Webcompat intervention to spoof the user agent string for this site.

Tom, is this possible?

Yeah, their script seems broken in strict ETP mode (I can't click on the cart icon at all), while in standard mode it doesn't appear to have any problems. But their intent is pretty clear:

      // Function to detect Firefox browser
    function isFirefox() {
      return navigator.userAgent.toLowerCase().includes('firefox');
    }

    // Run only in Firefox
      if (isFirefox()) 
        const fireboxPolicySection = document.querySelector('.firebox-policy');

We might as well do a UA override here. I'll see what I can cook up.

Actually, upon closer investigation I can't make heads or tails of what's going on here. I never get any message about ETP/Firefox from the site, and while I was able to reproduce a problem where clicking the cart button did nothing, I can't reproduce that now. It looks like maybe the site is not actually running the related code now?

This seems to be fixed with global baseline exception of rebuyengine (see https://etp-exceptions.mozilla.org/). @calin can you please verify whether this is also fixed for you? Thanks!
