Firstly hi.. For firefox go to tools and you will have option there to delete recent history..delete what you want to delete from there or all..Its as easy as that and for internet explorer I don't remember cause its been a long time since I had used internet explorer.. Have a nice day!

For Firefox, if you have the lastest version, you can choose which cookies to keep or delete. Go to Tools - Options... - "Privacy" tab. In the drop-down box, select "Use custom settings for history"; this will cause some options with check boxes to show. Next to "Accept Cookies from site" there's a button called, "Exceptions". This will allow you to list sites you don't want to get cookies from. Under "Accept third-party cookies", there's an option to "Keep until:". If you select "ask me every time", then you can always keep your cookies. And then if you want to delete certain cookies, go to "Show Cookies...". From there you can choose which sites you want to keep or delete the cookies from. I'm not sure about Internet Explorer though. I haven't used that browser in years.
