Firefox Quantum will not let me log in to Facebook.

more options

I can get the 'facebook login' screen, I enter my information in the required fields, but I cannot log in. I get a popup window reminding me not to use my facebook login information on 'non-facebook' websites (well, DUH), and below that are some of the email addresses that i have used in the past. Clicking 'log in' only re-loads the login page. How can i go back to the previous edition of Firefox until all the bugs are worked out of the latest version (Quantum)?? Thus far, facebook is the only website that Quantum has an issue with.

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:

In Firefox 54 and below:

  1. Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux).
  2. Select the Advanced panel and the General tab.
  3. Uncheck Use hardware acceleration when available.
  4. Close Firefox completely and then restart Firefox to see if the problem persists.

In Firefox 55 and above:

  1. Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux).
  2. Select the General panel.
  3. Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.

I did everything you suggested, but nothing has allowed me to log in to Facebook. I'm not sure how the actions affected the other sites i visit regularly (some have detailed login procedures and protocols). Thank God I still have IE on my computer, although it's a bit slower than Firefox. Fix the issues, I'll be a happy guy.
