I am finding older search terms/phrases I have used in the past appearing on other sites. For example I use Google (with Firefox) to search for something and days/weeks later I am on another site and sometimes when I begin typing in that site's search box, it autofills with search terms previously used. The sites are not even remotely similar are linked. I use CCleaner daily and have my Browsing history off. Where might I find out how to stop this or delete the search terms? Thanks for any help...it's annoying.
