Fix login issues on websites that require a username and password

If you find that you can’t log in to a website that requires a username and password, follow the steps described in this article.

Enable cookies for the website

Make sure that cookies are enabled for the site in question.

If you changed any settings, try logging in to the site again.

Clear history for that site

The cookies and temporary data already stored on your computer may be causing the problem. Delete them, then test for your problem:

  1. Click the menu button menu button to open the menu panel. Click History and then click the Manage History bar at the bottom to open the Library window.
  2. At the top right corner, type the name of the website you wish to forget in the Search History field, and press Enter.
  3. In the resulting list, right-click on the site you wish to forget, and select Forget About This Site. History Win6
  4. Close the Library window.

Clear all cookies and the cache

If deleting cookies for the site with the problem did not fix the error, clear all the cookies stored on your computer and clear the Waterfox cache:

  1. Click the menu button menu button to open the menu panel.
  2. Click History and select Clear Recent History…
  3. In the Time Range to clear: drop-down, select Everything.
  4. Below the drop-down menu, select both Cookies and Cache. Make sure other items you want to keep are not selected.
  5. Click OK.

To learn more about clearing cookies, site data and cached web content in Waterfox, see Clear cookies and site data in Waterfox.

Check add-ons

Some extensions can cause problems with logging in to websites, especially extensions associated with certain websites. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Waterfox problems.

Security application is blocking cookies

Some Internet security and privacy applications have features that block cookies. Check the documentation that came with your software or visit the software provider’s support site, to see if your application includes a cookie control feature and how you can change those settings.

Remove corrupt cookies file

If you can’t log in to websites after removing the cookies associated with it, clearing your Waterfox cache, and trying with your extensions and plugins disabled, and have checked security software, you may have a corrupt cookies file in your Waterfox profile folder.

This will remove all your stored cookies and essentially log you out of all saved sessions on all websites.

  1. Open your profile folder:

    • Click the menu button menu button, click Help and select Troubleshooting Information. The Troubleshooting Information tab will open.
    • Under the Application Basics section next to Profile Folder, click Open Folder. Your profile folder will open.
  2. Click the Waterfox menu menu button and select Exit.

  3. Delete the cookies.sqlite file and any cookies.sqlite-journal files.

  4. Restart Waterfox.
