When I type about:config, a list shows up how do I delete an item from that list?
How do I delete items that come up when on the address line I type About:config

You can reset a pref to the default value via the right-click context menu.
Then that pref will be removed if you close and restart Firefox in case that pref doesn't exist by default (i.e. type is string and shows nothing in the value field after the reset).
Prefs that have a default or a user set value can't be removed.
- Use the Search bar at the top of the about:config page to locate preferences more easily
- Preferences that have been modified and do not have the default value show as bold (user set)
- Preferences can be reset to the default via the right-click context menu if they are user set
- Preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean) or by double-clicking the line with the pref
- Preferences can be created via the right-click context menu: New -> String, Integer, Boolean
