If you want to remove stored logins from Mozilla Firefox, the process is simple once you know where Firefox Password Manager keeps them.
This guide explains how to delete saved passwords from Firefox on desktop and mobile, and what to check before you remove anything important.
Why Delete Saved Passwords from Firefox?
Firefox can store usernames and passwords to make sign-ins faster, but saved credentials are not always ideal.
People often delete them for privacy, security, troubleshooting, or to clean up outdated accounts.
Common reasons include:
- Signing out of a shared or public computer
- Removing old passwords after changing accounts
- Fixing login conflicts caused by stale credentials
- Reducing the risk of unauthorized access if a device is lost
- Keeping Firefox Password Manager organized
Firefox uses built-in password storage tied to your browser profile, and if you use Firefox Sync, those entries may also appear on other connected devices.
That makes it important to know exactly what will be deleted.
How to Delete Saved Passwords from Firefox on Desktop
The desktop version of Firefox for Windows, macOS, and Linux stores passwords in the built-in Password Manager, also called Saved Logins.
You can delete individual entries or clear them in bulk.
Delete one saved password
- Open Firefox.
- Select the menu button in the upper-right corner.
- Choose Passwords or Logins and Passwords.
- Find the site you want to remove.
- Click the three-dot menu next to that entry.
- Select Delete.
Some Firefox versions may ask you to confirm the removal.
Once deleted, Firefox will no longer autofill that login on the selected device unless the password is saved again later.
Delete multiple saved passwords
- Open the Firefox Password Manager.
- Use the search bar to locate specific websites if needed.
- Select the first saved login you want to remove.
- Hold Ctrl on Windows or Command on Mac to select multiple entries, if supported in your version.
- Open the action menu and choose Delete.
If multi-select is not available in your build of Firefox, remove entries one at a time.
This is slower, but it reduces the chance of deleting the wrong login.
How to Delete All Saved Passwords in Firefox?
If you want to clear every stored login from Firefox, use the Password Manager or Firefox settings, depending on your version.
This is useful before selling a device, repurposing a profile, or doing a full privacy reset.
Clear all stored logins from Password Manager
- Open Firefox and go to Passwords.
- Look for a bulk action, such as a menu item labeled Remove All Logins or a similar option.
- Confirm the deletion when prompted.
If your version does not offer a one-click bulk delete, you may need to remove entries manually.
Another approach is creating a new Firefox profile, which starts with a clean password store, but that also removes other profile data unless you migrate it carefully.
Before clearing everything, export any credentials you still need.
Firefox can save an encrypted or CSV export depending on the workflow available in your version, and a CSV file should be protected carefully because it may be readable in plain text.
How to Delete Saved Passwords from Firefox on Mobile?
Firefox for Android and iPhone also includes saved login management, though the menus differ slightly from desktop.
The core idea is the same: open saved passwords, select the entry, and delete it.
Delete saved passwords on Firefox for Android
- Open the Firefox app.
- Tap the three-dot menu.
- Go to Settings.
- Tap Logins and passwords or Passwords.
- Select the website entry you want to remove.
- Tap Delete.
Delete saved passwords on Firefox for iPhone
- Open Firefox on iOS.
- Open the menu and go to Settings.
- Choose Passwords or the Firefox password section.
- Select the saved login.
- Delete the entry and confirm if prompted.
On mobile, biometric protection such as Face ID, Touch ID, or device PIN may be required before you can view or remove stored passwords.
This is part of the security design of Firefox Password Manager and the device operating system.
Will Deleting a Password Remove It Everywhere?
That depends on whether Firefox Sync is enabled.
If Sync is active, deleting a saved password on one device can remove it from other Firefox devices connected to the same Mozilla account.
Before deleting synced credentials, consider these points:
- Changes may propagate to desktop, Android, and iPhone
- Removed entries may disappear from any device using Firefox Sync
- Other devices or password managers may still keep a copy if they were not synced with Firefox
If you only want to remove a password from one device, check your sync settings before deleting it.
You may need to disable Password Sync temporarily or use a different browser profile.
How to Stop Firefox from Saving Passwords in the Future?
Deleting old passwords does not prevent Firefox from saving new ones.
If you do not want Firefox to store logins again, change the browser’s password-saving settings.
Turn off password saving
- Open Firefox settings.
- Go to the Privacy & Security section.
- Find the Logins and Passwords area.
- Disable the option to ask to save logins and passwords.
You can also manage exceptions so Firefox does not offer to save passwords for specific sites.
This is useful for work portals, shared accounts, or sensitive services.
Use a dedicated password manager
Many users prefer a standalone password manager such as 1Password, Bitwarden, Dashlane, or LastPass rather than storing credentials inside the browser.
A dedicated manager often includes stronger vault controls, sharing features, audit tools, and cross-browser support.
What Else Should You Check After Deleting Saved Passwords?
Removing saved logins from Firefox is only one part of account hygiene.
If you are cleaning up a device or protecting an account, review related browser data as well.
- Autofill entries: Remove stored form data if needed.
- Cookies and site data: Clear sign-in tokens on shared devices.
- Downloads and history: Review browsing traces if privacy matters.
- Firefox Sync: Confirm password sync status across devices.
- Account security: Change passwords and enable two-factor authentication for sensitive accounts.
If you think a password may have been exposed, update it immediately and review recent sign-in activity from the service provider.
For high-value accounts like email, banking, or cloud storage, a password change should be paired with multi-factor authentication.
Troubleshooting Common Firefox Password Deletion Issues
Sometimes users think a password has been deleted, but Firefox still autofills it.
In most cases, the issue is related to sync, duplicate entries, or cached website data.
Firefox still autofills the login
Check whether the login exists in more than one Firefox profile or on another synced device.
Also verify whether the website stored its own session cookie or remembered your login through another browser feature.
The password reappears after deletion
If Firefox Sync is enabled, a connected device may be restoring the entry.
Sign out of Sync temporarily or delete the entry from every synced device.
I cannot find the saved password
Use the search box in Firefox Password Manager and try the exact domain name, such as the login subdomain.
Some sites store multiple variants, including mobile and regional versions.
I need the password before deleting it
Export the login list or copy the credential to a secure, encrypted password manager first.
Do not leave exported passwords in Downloads or email them to yourself without strong protection.
Best Practices for Managing Firefox Passwords
Firefox Password Manager is convenient, but it works best when paired with simple security habits.
Keep saved passwords limited to trusted devices, review your login list periodically, and remove entries you no longer use.
Helpful habits include:
- Using unique passwords for every account
- Turning on multi-factor authentication wherever possible
- Reviewing saved logins after a password reset
- Deleting credentials from old profiles and unused devices
- Monitoring sync settings in your Mozilla account
For users who frequently switch devices, browser-based password storage can be convenient.
For users who prioritize stronger security controls, a dedicated password manager may be a better long-term option.
