Hello, A couple weeks ago my Quickbooks Online software began requiring 2 tier authentication. This feature is disabled within the software settings and does not happen when using a Macbook. According to Quickbooks this issue is due to the browser (Firefox). I didn't change any setting prior to this issue. I did however reset to the default settings but the problem is not resolved. I've searched the Firefox settings for a solution but was unsuccessful. Can anyone help?

Thanks, Kathy

Hi Kathy, there is no specific Firefox feature for 2FA/MFA. Websites can require extra authentication if that is part of their security protocol, but I don't know why the site would treat different browsers or different operating systems differently.

One thing: after you complete 2FA/MFA, the site will set a cookie so that you don't have to do it again in the same browser. If the cookie is cleared, then you'll need to pass the challenge again.

Hi jscher2000, Thanks for the quick reply. I thought about the cookie issue, I have this website set to allow cookies. Couple confusing things, every log-in has a different login address and this wasn't a problem until a couple weeks ago. Anymore thoughts?

Thanks Again, Kathy

If there are sub level domains involved then best is to create the exception for the top level domain. I.e. https://mozilla.org includes https://support.mozilla.org


In case you use "Clear history when Firefox closes" or otherwise clear history.

  • do not clear the Cookies
  • do not clear the Site Preferences
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
  • clearing "Cookies" will remove all selected cookies including cookies with an allow exception you may want to keep
