Cannot log into Twitter on Firefox anymore

At first I was getting the something not wrong but don't fret we'll give it another shot message so I looked online and added Twitter to a block list and cleared all my cookies. This got rid of that message and I was able to get to the login page but when I go to login it still won't let me. I know the password is right (it also doesn't say anything like incorrect username/password). Someone in another forum had mentioned going into configs and flicking something from true to false or vice versa and that also didn't work. Most places I look just say the same old thing about cookies. It works perfectly fine on the mobile app and Chrome still but I prefer Firefox. I'm out of ideas.

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" for websites that cause problems:

  • Options/Preferences -> Privacy & Security
    Cookies and Site Data: "Manage Data"

  • Options/Preferences -> Privacy & Security
    Cookies and Site Data -> Clear Data -> Cached Web Content: Clear

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
