How to Edit Autofill on Firefox (Usernames and Passwords)

I’m sure you know that you can edit the autofill list of websites that Firefox uses to populate your Website Passwords and passwords for you, by clicking on the Edit option at the bottom of the autofill window. You can add sites to your list, remove sites from your list or edit the order(s) of your sites. If you’re not sure what I mean, just try it out and see what happens.

Are you someone who has trouble remembering their passwords? Do you have to type them in every time you open a new site? Or are you like me, and you often forget your usernames and passwords, simply because they are so long? This is an unfortunate problem that most of the time we just accept as a fact of life. However, with a few simple changes to your Firefox browser’s settings you can prevent this from ever happening to you again.

While autofill is a pretty handy feature, there is a lot of debate around whether it’s a security issue when it comes to storing passwords. That’s because, as the name suggests, it automatically fills in usernames and passwords for you. The thing is, you can turn it off in the settings. After all, Firefox can be a bit of a resource hog, and we all know how much we loathe bugs that hang and crash our computers. So, here’s how to turn autofill on and off.

Firefox, in addition to Chrome and Safari, is still quite popular among Windows 10 users. Autofill is a useful feature in any browser, but understanding how to modify autofill in Firefox is particularly useful. I mention this because it’s something that almost everyone, in whatever browser, will need to perform at some time.

To delete or modify usernames and passwords stored in Firefox, choose Logins and Passwords from the three horizontal lines in the upper right corner. Remove or update the linked account information to the right of the account you selected on the left.

If my quick response wasn’t adequate, here’s a comprehensive step-by-step tutorial to help you modify or delete autofill information in Firefox.

What exactly is autofill?

Autofill is a browser function that adds your stored login credentials to a website’s login page automatically. This nearly makes getting into your online account on any website a breeze.

Your login information is stored in the cloud with Firefox Sync, giving you more flexibility and security when storing your passwords.

This means you can use any fresh browser installation to log in to Firefox Sync, and you’ll have immediate access to all of your login credentials for all of your accounts.

You’d have to manually enter your username and password into every login page if autofill wasn’t available.

I don’t know about you, but the idea of all those manual logins doesn’t seem like the proper way to utilize technology in this day and age, unless I’m working on someone else’s computer.

How to modify or erase Firefox’s autofill login data

You may then choose Edit or Remove from the two choices in the top-right corner.

Before deleting any account autofill items, double-check that you have the proper login credentials. There’s minimal chance of getting the thing back after it’s been removed.

You may modify the username and password for that account by clicking the Edit option.

Before exiting the browser tab or window, be sure you click Save Changes.

You will be asked whether you want to delete it if you click the Remove button. It will be permanently deleted after you indicate that you want it gone.

Firefox Autofill has been replaced with a safer and more versatile alternative.

There’s a free alternative to Firefox’s autofill function that saves your usernames and passwords in the cloud in a secured vault.

This way, you won’t have to worry about whatever browser you’re using since it’s compatible with all of them, and it also gives you access to your vault via a web browser page login.

It also includes a Microsoft Windows, Android, and iPhone app that you can download. As a result, you are not restricted to using just a browser.

It will autofill login credentials for you after you have added the login information, much like Firefox or any other browser.

For me, not having to use one browser for all of my online accounts offers me the flexibility to use whatever browser I choose, whenever and whenever I want.
