Firefox 86.0 (64-bit) on macOS When I start to type the URL for an address I use often, for example bar for barnesandnoble.com, I always get barefootyoga.com as a suggestion. I've never visited this website. It's not in my history. I have no idea what it's popping up when typing bar used to autofill barnesandnoble. When barefootyoga pops up in the URL as a suggestion, I click SHIFT + DELETE, but barefootyoga appears the next time I type bar. (This is happening for almost all other websites where autocomplete used to work correctly--this is just one example.) I've cleared all history for all time and restarted browser. Same result. After relaunch, I fully typed barnesandnoble.com and visited the website to get it back in history. I opened a new tab, typed bar, and barefootyoga began to autocomplete In Preferences, I get the same unwanted result with these settings: Search > Search Suggestions > Disable/renable "Provide search suggestions" Privacy & Security > Address Bar > All check boxes selected ''except'' for search engine In about:config, I scanned options for browser.urlbar, but nothing looks like it would resolve this issue I feel as if I am missing something obvious.
