Hi there, I'm running the latest Firefox here on my trusty old Intel Mac Pro on Big Sur. Keeps on truckin'. However, just now I looked and the Mac said it had "Rebooted because of a problem". All my open tabs came right back up in Firefox and my Search History is fine. But when I click on the Address Bar I no longer get the list of top sites that I often visit, NY Times, banking, social media, etc. Why would that suddenly just disappear, and how can I get it back? Thanks for any tips! - Steve ''Moderator note: This question has been edited to correct the formatting.''
