I don't like it when webbrowsers keep passwords and usernames in their system. for example gmail, you type in your username and password and it remembers it. i don't know how to undo this.

In gmail, you would normally only see the accounts' name if you typed in the first letter of it and it pops up all the emails logged in on that computer with the first letter. Mines a B, but that's easy for anyone to know if they have my email. I would really like it if someone could help me fix this password/username lock thing.

I don't suppose it makes you any happier that you just need to double-click rather than guess the first letter of the user-id.

The user-id is remembered in cookies. You can remove cookie through Tools > Options > Privacy

The password connected to a user-id is collected upon successful use and clicking on yellow security bar. You can remove password through Tools > Options > Security

If you have a Master Password then it will restrict additions and deletions of passwords until a Master Password was entered for the session. Changes to the master password or show passwords require additional entry of master password at time of use.

If you don't want cookies or passwords saved because other have access to your computer that is what Private Browsing ("Ctrl+Shift+P") is for

Anyone with physical control of the computer owns it.
