After searching in the browser bar, and then getting results, i click on hyperlinks from the results and new tabs open. I explore the subsequent open tabs, and then at some point, the search functions quit working in all tabs, and i need to restart firefox to correct the issue (searching in the main browser bar ). If i type an actual address - it will sometimes "clear the glitch" and the "searching in the broswer bar" may start working again... Any ideas why the search function would not respond from time to time?
