Clear Passwords, Private Data, Cache, Cookies and History in Browsers

Often, browsers such as Internet Explorer or Firefox store data in their cache. Data such as browsing history, form data (your name, address, phone number etc. that you filled in while buying stuff from amazon!), passwords and snapshots of web pages are collected. Now, if you were a paranoid user, you'd probably disable all these features.

But they were simply put in there to make our life much more easier. Internet Explorer (or any other browser for that matter) stores our passwords so we'd never have to type them again. It stores our webpages so that we'd never have to wait for it again. It stores our name so that we'd never have to remember it again. Yes. That's how much we can leave to the computers to remember.

However, what do you do if you don't want the browser to remember it? This article explains how to clear your private data for Internet Explorer 7, Internet Explorer 6, Mozilla Firefox and Safari.

Note: If you are using Internet Explorer or Firefox or Safari or any browser in a public setting (office, school, libraries, community centers), these tools menu and settings mentioned below are usually DISABLED! The only way to make sure that the computer doesn't remember your password when you're checking your e-mail is to make sure the 'Don't remember my password box' is unchecked! Most organizations make sure that your data is deleted every time you log off, but better to be safe than sorry!

You might also want to use this method to make Internet Explorer or Firefox run faster if you find that your browser is running too slow, and you're using Windows XP or Vista.

  1. How about explaining what's in the cache? And what the other components contain as well. Can I keep my UIDs and passwords, but not the junk that other sites put there?

  2. @ Anonymous - the cache contains data that the browser saves on your computer about a website that you visit. The logic behind doing so is that when you visit the same website again, you don't have to download all the data again. Consequently, the webpage loads much faster the second time you visit it.

    The Cache doesn't contain your user IDs and passwords... it just contains website data or file data (depending on the website you visit). For example, if you want to check out what's in your Cache in Firefox, just type in


    in the address bar (that's where you type in the website addrress...) and firefox will show you a list of all files stored in your cache.

    If you want to keep your password and so on, make sure you uncheck the passwords box when click "Clear" or Reset or just click the "Delete cache", "delete history" etc.. buttons on Internet Explorer or whatever browser you have.You can safely delete the cache, history and cookies (cookies keep you logged into the website.. but since the browser has your password and username anyway.. they're not completely necessary) without affecting your UIDs and passwords.
