I have been attempting to delete my history library from December of 2009 to April, it is all the search history I apparently have in my library. I've cleared the history multiple times (in and out of privacy mode to test the difference), I run firefox in privacy mode normally, I even tried a CC cleaner. I'm very frustrated at how difficult this is. I can go into a month and delete it website by website but with thousands for each month this is far too difficult to do. There has to be something I'm missing, any advice? Do I need to reinstall? I've tried going into the program files to find the history but no luck. To summarize: 1. Yes I've tried tools, privacy, delete browser history, many times and in and out of privacy mode. 2. I've tried deleting the months in the library, but nothing happens. 3. I've tried clearing the history manually and with cleaners. Help please!
