Is there anyway to delete your browsing history on your computer individually?

What do your mean by saying "individually"?

As I know, to delete browsing history in Firefox: click Tools, there is an option that lets you to delete history files, that's it.

Note: browsing history can contain the search history, internet browsing history, cache, cookies, cache, auto complete form history, etc. If have deleted the auto complete form history, and you have not remembered the passWord, then you can't enter that web site next time unless you have a new account.

In the link there is a site to some tool named Privacy protector, it may helps.
