Steps to Reproduce: 1. Launch Firefox (and add Sites shortcuts) 2. Do not navigate to any website 3. Observe network activity using Process Monitor or clash verge

Expected Behavior: - Opening about:home should not establish TCP connections to remote sites unless the user interacts with them.

Actual Behavior: - TCP connections are observed immediately to sites listed in Top Sites shortcuts, even without user interaction.

Notes: - Disabling DNS prefetch, speculative preconnect, and predictor settings does not prevent these connections. - Extensions have been ruled out, I can distinguish darkreader.org(extention) mozilla.org(update) and reddit.com(your sponsor url) from *.edu.*(my shortcuts), DON'T mention that. - Connections occur before any page navigation or clicks. - I suspect that Firefox may attempt to load site icons (favicon / tile thumbnails), but this is unconfirmed.
