What have you tried to clear this ?

Note firefox by default keeps; I think , 180 days history; although that may be changed. See Cannot clear Location bar history

the history has been there for much longer than 180 days and i see nothing mentioned of that default. thanks for your reply though.

If you wish to stop the History items showing in your location bar dropdowns my original post gave alink to an article explaining you to do that : by using your Privacy settings . If that fails to work then look at How to fix preferences that won't save

Firefox keeps say your last 18o days history, so in 10 years time it will still be showing history, even if it is still the last previous 180 days.

Re the variable expiry date for history: this was settable form the main User Interface until very recently, up to about version 3.5, it must now be set using about:config

• see http://kb.mozillazine.org/Browser.history_expire_days

i could clear my history i just could clear what was in my drop down search list. i did find out how too and i appreciate your reply.

Glad you seem to have solved the problem. If you have remaining related problems post again, otherwise you may like to mark the problem as solved.
