Opera is a free, complete browser and a great option for those who do not want to use Internet Explorer. It has an easy-to-navigate toolbar, tab browsing support, and customizable settings. Opera search history is managed from a dedicated window in the ‘Tools’ menu. You can delete all history and saved settings for everything (web pages, cache, etc.) or just specific things like search history.
