How to Remove All Saved Logins from Firefox Browser

When you enter login data on a website, Firefox prompts to save it inside the web browser for later use. This is a really useful feature as you do not have to type the passwords all the time in order to login again to those web sites, apps or services. These login details are saved inside the Firefox user profile and is also encrypted if you have protected all the logins using a primary password (previously called the master password).

If you have saved some logins in your Firefox user profile and want to remove them all, then Firefox has added a new feature in Firefox version 85.0 using which you can quickly remove all the saved passwords in just one click. Here is how:

  1. Launch Firefox web browser and click on the menu icon (three lines near the top-right corner).
  2. From the menu that appears, select Logins and Passwords.
  3. On the Logins screen, click on the menu icon (three dots) and select Remove All Logins. You may have to enter the primary password before the logins are erased.Firefox Remove All Logins

But this is not the only way to remove all the logins from your Firefox profile. Instead of using the feature mentioned above, we can also erase the files in which the logins data is stored. This method works even in Firefox versions before 85.0. Here is how:

  1. Launch Firefox web browser and enter about:support in the address bar.
  2. Click on the Open Folder button to open the Firefox profile folder in Windows File Explorer.Firefox Remove All Logins
  3. Close all Firefox windows by pressing the hotkey Ctrl+Shift+Q.
  4. In the profile folder that we opened in step 3, locate three files: key4.db, logins.json and, logins-backup.json and then delete them.Firefox Remove All Logins

So these are two methods of completely removing all the saved logins from your Firefox web browser. The first method works only in version 85.0 and above while the second method works in some of the older versions too.
