Hi II am a relative computer novice and I am confused by the concept of deleting cache and cookies. I am having trouble with Firefox browser on Vanguard website. I was told to clear my cache and/or cookies. I don't currently store any Vanguard passwords on my computer. However, I’m afraid that if I clear cache or clear cookies I will inadvertently remove the passwords for all my other websites. Is there a way to clear cache and clear cookies without deleting passwords?
