How do I delete the programs I no longer use or have looked into (example a bank I used to use and closed) how do I take that off my list
I have cancelled some accounts and want to remove the address from my computer ie Cashmere Bank how do I do that
Your title asks about programs, but your question details speak of accounts and addresses. Please clarify what you really need help on.
If I assume you're trying to remove a web address from your list of bookmarks, click Bookmarks > Show all Bookmarks > select the one to be deleted and click Delete.
Firefox [or (Alt) > Tools] > Permissions Manager.
There is a search bar top left. Enter part of the site name so that all listings can be shown. Left click the first item. At the top right there is a button labeled Forget About This Site. Do this for each entry for that site.
"Forget about this site" will remove history, bookmarks, cookies, any site-specific permissions you saved, etc. You should only need to use it once per site. If you have a huge amount of history, it can be slow to run, so don't panic if Firefox seems to lock up for 20 seconds, let it run.
