Deleting saved passwords

I have an e-mail password that is being saved in my browser for my Google e-mail (gmail) account. Is there anyway of deleting/removing it within the IE and Mozilla browsers so it doesn’t automatically show up after I type in my username. I also want to do it without having to reset ALL the passwords within the browser (through IE tools and internet options)
