T-Bird one Yahoo of six accts, repetitive “ENTER CREDENTIALS” My T-bird release: 144.0.1 (64-bit) Desktop: WIN 11 Pro – with all updates

For the last few days, I have not been able to obtain emails on my desktop T-Bird for one of my six Yahoo accounts. And, I cannot send any emails from the account

BUT, I can access the target Yahoo email account via my desktop Firefox, via Android T-Bird and via Android/Firefox. And all incoming and outgoing emails are present. Stymied, I changed the Yahoo acct password. After the change, these three work domains perfectly as before. And again, all incoming and outgoing emails are present.

BUT, the repetitive error with my desktop T-Bird for the one Yahoo account persists. The POP-UP provides a long string in the URL window and the only text shows: “Edge: Too Many Requests” >>>>>>>> I’m not using EDGE [Yahoo must use EDGE for the login error POP-UP] The window in the bottom Task Bar displays: “Enter credentials” [repetitively – ad nauseum].

This is the copy of the Yahoo URL in the POP-UP: https://login.yahoo.com/?src=thunderbird&client_id=dj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--&crumb=mdAGY49jGd8&login_hint=name_of_email_acct%40yahoo.com&redirect_uri=http%3A%2F%2Flocalhost&pspid=954010027&activity=thunderbird-imap&done=https%3A%2F%2Fapi.login.yahoo.com%2Foauth2%2Fauthorize%3F.scrumb%3D0%26client_id%3Ddj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--%26redirect_uri%3Dhttp%253A%252F%252Flocalhost%26response_type%3Dcode%26scope%3Dmail-w I changed my email account name in the display above to: name_of_email_acct; all else is verbatim.

For clarity all six accounts work without encountering "Enter credentials" on the desktop via Firefox, my android via T-Bird app, my android via Firefox. Five of the six work on my desktop T-bird.

I did not add any extensions in the last week. I did disable all extensions (and restarted) with no change in behavior. I put a 25 cent piece on the keyboard to appease the computer gods – no change.

Yup: cleared cache and cookies. Deleted password from desktop T-Bird repository, but the new one is not recorded. Changed authentication from OAuth2 to Normal and back again- no change

Yes, I waited multiple hours to try again, with no luck.

Thoughts ????

I would like to know how the Firefox CVEs are affected on its version which are mentioned in NVD.

Let take mfsa2025-59, for example CVE-2025-8040, as per the NVD its says Firefox ESR < 140.1 is affected so does that mean it affect all the version which are lower than 140.1 which included the ESR 128 and ESR 115 versions or just the ESR 140 version series? then it raise on more question check this cve-2025-8029 in NVD it has specifically mentioned it only affect "Firefox ESR < 128.13, Firefox ESR < 140.1" and not the ESR 115 versions. Could anyone confirm it does not affect the ESR 115 versions or it affect all the versions? Now check this one cve-2025-8027, NVD clearly mentioned "Firefox ESR < 115.26, Firefox ESR < 128.13, Firefox ESR < 140.1" are affected so what I understand is that if the Firefox ESR 115 is vulnerable to any CVE it would be mentioned in the NVD specifically.

My point is that if any Firefox CVEs are listed in NVD and it specify only one version like “Firefox ESR < 140.1” what does that mean? Does it affect all the versions which include ESR 128 and ESR 115 or just the ESR 140 series version only affected? If any CVEs are affected on the ESR 115 and ESR 128 does Mozilla specifically mentioned those versions are affected right? Just like its mentioned in the cve-2025-8027

Any help would be appreciated to clarify this.

Hi, I'm using Firefox 142 on Ubuntu 24.04. It's a fresh install. I cannot sign in icloud.com with Firefox even though it works with other browsers like Brave. I deleted all cookies and site data and disabled extensions (KeePassXC). It doesn't help. I tried in new private window. No success. I copy my password from a password manager, so, no, I haven't mistyped it.

Here's what I do:

1. Open Firefox and go to icloud.com
2. Click on the "Sign In" button
3. Enter my Apple-ID and click on the arrow on the right end of the "Email or Phone Number" field

At this point Brave behaves differently than Firefox. See below for how Brave behaves.

Firefox: -> A "Password" field appears (no buttons "Continue with Password" and "Sign in with Passkey")

1. Enter my password and click on the arrow on the right end of the "Password" field

-> Error message "Failed to verify your identity. Try again" appears. See icloud.png

Brave: -> Two buttons "Continue with Password" and "Sign in with Passkey" appear. See icloud-with-brave.png

1. Click on button "Continue with Password"

-> A "Password" field appears.

1. Enter my password and click on the arrow on the right end of the "Password" field

-> 2FA code is sent to my iPhone -> "Two-Factor Authentication" form opens... etc. complete sign in successfully

Please help!

Unfortunately I cannot attach the HAR file from the login sequence because the password is included. However, I attached some screenshots from the Web Developer Tools. It seems to me that the login flow with Firefox is broken. I can't tell who's to blame, Apple of Firefox. The error message with Firefox is always the same, no matter whether I enter the correct password or rubbish. In Brave, however, there is a more precise error message when I enter a bad password. See icloud-with-brave-wrong-password.png

Firefox had been a safe haven for anti-AI, and used to be my go-to search engine. If this AI bullshit continues, no one will respect or use the browser. Stop implementing AI garbage that steals data

My browser is not working as it should. Several sites do not work anymore and the browser keeps crashing. I'd like to refresh the browser, but the button is missing. I tried going to troubleshooting mode, but the button is not there either.

Not sure if uninstalling would do the same thing? Just not sure what is the best way to refresh. Thanks for any help!

I am very disappointed to learn that Firefox is moving forward with AI integration. I use this browser specifically because there is no AI. AI tools are a drain on public resources such as clean water and electricity, and the data centers that host the AI servers are a burden in many ways on the communities where they're built.

Additionally, I am concerned that the AI will turn all of our browser history into an AI slop ad factory where our data is more easily collected and sent off to generate more ads.

If AI is integrated into FireFox, I will no longer use this browser, even if the AI can be "turned off".

Is there any way to keep AI out of FireFox?

Rarely fetches emails automatically at 15 minutes. I can fetch manually. This has been going on before the last update. I haven't changed any settings. Sometimes it fetches when I open the app. Other times I must fetch manually. Also, we should be able to fetch sooner than 15 minutes.
