I can't log into NS - blank page at the "Two factor login challenge" page

AI generated answer (using internal Slack threads):

It seems like you're experiencing an issue with the Two-Factor Authentication (2FA) page not loading when trying to log into NetSuite. This issue has been reported by other users as well, and it seems to be browser-specific. Some users have reported that the 2FA page doesn't load in Firefox, but works fine in Chrome. One user mentioned that they had some custom JavaScript running on all NetSuite domains, which was causing an issue on the 2FA page. Disabling this custom JavaScript resolved the issue for them. Another user reported an "unexpected error" when trying to log into the NetSuite Support Center. This issue was resolved by clearing the browser cache. If you're locked out of your account and unable to reset your 2FA, it's recommended to use backup codes if you have them. If you don't have backup codes and you're unable to receive a text with a code, it's suggested to switch to an app like Google Authenticator for 2FA, which works completely offline. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
