Changing Stored Passwords on Firefox (Mac) and Windows

Changing stored passwords using Firefox browser is fairly simple. For those with Windows PCs, see caveat at bottom.

Click on the ‘Security’ tab and click on the ‘saved passwords’ button on the bottom right. A new window will pop up (see below) – to see passwords, press the ‘Show passwords’ button on the bottom right.

Note: if you have a lot of passwordsstored on your site, you can find the password for your site just by typing the url of the site in the ‘Search’ field at the top.

Firefox: Changing Passwords on PC – Important Caveat

It’s true that there’s a simple procedure within Firefox for changing passwords or deleting them altogether. But there’s an important caveat: People who have a Windows PC for many years may end up installing numerous versions of Firefox. Some of these versions leave behind old passwords which are a security vulnerability.

There’s a very good utility called SIW or System Information For Windows. It’s free and lightweight, and can be installed portably:

After installing it, run it and scroll down the left side. Click on the item labeled “Passwords” or “Secrets.” This might reveal a bunch of old Firefox logins and passwords left behind from previous installs.

If so, locate folders which look something like this:

Documents and Settings\Foo\ApplicationData\Mozilla\Profiles
Documents and Settings\Foo\ApplicationData\Mozilla\Firefox\Profiles

Of special concern are these files, buried a couple of levels deep in the Profiles folders:


Delete them and SIW should no longer find any Firefox passwords. Of course, don’t delete your current passwords!

Note: If SIW still finds old Firefox passwords, that probably means you didn’t delete the above files for each user.

Tip: Always use a master password in Firefox, or your site passwords will be easy to hack.

Creating proper internal links


Images are the same: .. image:: /images/vasudevaserver.gif

This is bad: /images/vasudevaserver.gif/

The bottom line is: Never add a trailing slash!

Also, please make sure images always have the type of file at the end (.jpg or .gif)
