I am aware of the method to delete web history but it seems not to work. I want to delete all past history. However, when I go back (one page at a time,by clicking the arrow pointing to the left) from any of the ten tabs at the top of the Safari page, all sites visited under that tab reappear in reverse order. So, it seems the deleting of web history is not working. Of course, I may be doing something wrong, but I don't know what. Can anyone please help?
At one point I saw page which suggested (when the web history was not being deleted) to "clear the cache and cookies on your browser" but gave no method on how to do that. So, in addition I need help on that also.
Finally, I have not discovered how to retrieve the little gear near the top of the Safari page which, when touched, drops down the menu whereby one can get access to web history. It "little gear" shows up sometimes, but not always.
Thanks for any help.
