Firefox is one of the big three browsers with Chrome and Microsoft Edge, and it’s one of the easiest to customize. This includes a huge range of security features and tools to make life easier – including one of the slickest password managers around.

This blog will explain how to delete all of your saved passwords in Mozilla Firefox, down to the very last site. That way, you can wipe the slate clean and ensure that thieves or cybercriminals won’t find it easy to access all of your accounts.

But before we get into the step by step guide, you might need a little more convincing that erasing why knowing how to delete saved passwords on Firefox matters. And it’s actually a really good question – with some answers that every Firefox user should consider.

Why it’s important to delete your saved Firefox passwords

Browsers routinely save passwords for a whole range of online services, from apparel stores and chat rooms, to sports broadcasters, newspapers, and social media networks. Much of the time, it’s a very useful feature, allowing Firefox users to access sites instantly, without needing to laboriously enter their password every time.

But it can also be a major security problem. There are a few reasons for this. Firstly, if your computer or smartphone is stolen, the passwords stored by Firefox could become a huge liability. They aren’t encrypted or protected in any way – allowing thieves to access whatever sites you use.

It should be noted that some sites are not included in browser caches. For instance, online banking credentials aren’t stored. But the details that are stored can still help criminals access your banking account. Much of the time, our passwords vary very little – and other accounts include plenty of valuable personal information. This information can be used to steal our identities or mount sophisticated social engineering attacks.

Moreover, if you want to sell your computer without wiping the hard disk, it may be a good idea to make Firefox delete saved passwords. That way, the next user won’t be tempted to take advantage.

Finally, it’s just not necessary for Firefox to store saved passwords. Instead, you can use encrypted password managers to store unique passwords securely, and link them to your browser – a much safer solution.

So let’s move onto the main question here: how to delete saved passwords on Firefox.

How to delete saved passwords on Firefox: a simple step by step guide

If you’re wondering can Firefox delete saved passwords, the answer is “absolutely, yes.” But if you want to erase all of your passwords completely, you’ll need to follow certain steps. Here’s how it’s done:

Firstly, you’ll need to prepare to delete your saved passwords. There’s always a risk that you’ll reconsider when deleting this kind of data, so if you have any doubts, make a note of your passwords. Even better, write them in a .doc file and turn it into an encoded .zip file with a package like WinZip. That way, they will be available for you to use in the future, but inaccessible to malicious outsiders.

Now let’s move onto deleting your Firefox passwords.

1. First, load up your browser.

2. Next, head to the “Menu” button in the top right-hand corner, and choose the “Options” link.

3. Choose the “Privacy and Security” option from the next menu.

4. Now, go to “Saved Logins.” Let’s assume you want to delete all of your Firefox passwords. In that case, you’ll need to pick the “Remove All” option on the “Saved Logins” tab.

5. If you want to remove passwords one by one, just choose the login you want to remove, then press the “Remove” button. It’s also worth noting that you can use the “Show Password” button to remind yourself of your passwords before you delete them. You may be surprised by which ones are still held by your browser.

6. Press “Close,” and you’re all done.

Now, let’s assume you are changing your browsing habits and don’t want Firefox to save any passwords in the future. In that case, return to the “Logins & Passwords” section of the Preferences menu.

You should see a toggle marked “Remember logins for sites.” Just untick the box, and you won’t need to worry about how to delete saved passwords on Firefox ever again.

Can I recover my stored passwords if I reconsider?

Sometimes, we all make mistakes and want to backtrack. But if you’ve made Firefox delete saved passwords, is there a way back?

In theory, you’d hope it would be difficult. If you could simply reinstate deleted passwords, it would definitely make life easy for criminals who steal laptops.

And that seems to be the case. Older versions of Firefox made it much easier to recover passwords, but since 2015 that hasn’t been the case. So it’s safe to assume that your deletions are permanent – which is just the way it should be, and why backing up passwords is a sensible option.

Are there alternatives to deleting my Firefox passwords?

In many cases, users won’t want to delete all of their passwords. That’s understandable, especially if you’re one of those people who use 50+ different retailers and have accounts on every conceivable social media network.

If that sounds like you, there is an alternative. Firefox allows you to set a “Master Password” which governs access to the Password Manager. This should place an impenetrable barrier between your passwords and thieves should disaster strike.

To set a master password, head to the Preferences menu we directed you to earlier. Now, instead of choosing “Saved Logins,” flag the box next to “Use a master password.”

Enter a strong password (Firefox will give you some guidance about how you’re doing), and then press “OK.”

Make sure your password security is as tight as can be

If you regularly work on the move or have any worries about losing passwords to thieves, knowing how to delete saved passwords on Firefox is an essential skill.

Hopefully, this guide will set you on the path to perfect password security. But remember, focus on strong passwords, change them regularly, and keep them totally private. Wiping your Firefox saved passwords is just one component of good password security, but it’s a good place to start.
