I can't log out of Twitter, even when I click 'log out' and delete all active sessions from all time and restart Firefox.


I have tried the following:

about:config browser.sessionstore.privacy_level set it's value to 1 {It may not work for all HTTPS sites but I have tested it on facebook,gmail and it worked.} signon.autofillForms {double click it to set it's value false} {Prevents auto fill up of forms.Firefox won't autofill the name and password. You need to open the name list with a double click in the name empty field.} browser.tabs.warnOnClose {Make sure it's boolean value is true.}

about:sessionrestore {For session restore.}

I have also tried logging out manually, restarting the browser and have run out of ideas. When I come back to Twitter I'm still logged in, and I wish to log into a different account which Firefox simply isn't letting me do!

I have also unticked 'save passwords for sites' and I've noticed before I did that that there weren't any saved passwords in my saved passwords list anyway.

I had this problem on version 12, so I updated to 13 and still have the same issue.

I've restarted Firefox with add-ons disabled (safe mode) and I'm still logged in to Twitter

If a password manager is installed, it could be automatically signing you in.

You can check if this happens in a new profile. After the new profile opens, please look in Tools (Alt + T) > Add-ons for any default add-ons/helper applications related to software on the PC. If the new profile is okay, you can then Reset Firefox on the old (previous) profile via Help (Alt + H) > Troubleshooting Information.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.
