Firefox 網站故障

Hello. Yesterday, I deleted all the stored login information, such as cookies. Latter, I tried to make login, I filled my name and password. As usual, Facebook refuses to login, giving me a choice of extra steps necessary. I chosen to receive a security code on my e-mail. I copy and pasted it on the suitable place and click on the button to proceed.

That's when things stop working. It usually it works as expected, but now it just return to the login page, nothing filled. Bellow, an apparently relevant info the shows on browser console:

"ErrorUtils caught an error:

_.getClientCapabilities is not a function [Caught in: Passkey authentication failed during visibility callback]

Subsequent non-fatal errors won't be logged; see https://fburl.com/debugjs. Object { column: "1421", clientTime: 1774704924, extra: {}, guardList: [], hash: "ukkpfs", isNormalizedError: true, line: "86", loggingSource: "FBLOGGER", message: "_.getClientCapabilities is not a function [Caught in: Passkey authentication failed during visibility callback]", messageFormat: "_.getClientCapabilities is not a function [Caught in: Passkey authentication failed during visibility callback]", … } D_9oglqPD5n.js:79:56"

Hi,

Please try these standard troubleshooting steps that may resolve the issue:

  1. Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield Fx89ShieldIcon icon in the left part of the address bar.
    • If ETP is enabled, try disabling it.
  2. If the problem is not fixed, try clearing Firefox cache.
  3. If it does not help, try clearing cookies and data for the website you experience troubles with (warning: you will be logged out on this website).
  4. If it also does not help, try running Firefox in Troubleshoot Mode. If the problem doesn't persist, please follow the steps from this article to troubleshoot further.

Does any of the above help? Looking forward to your update on how it goes!
