Hi, Just got computer back from shop where - rather than upgrade - they did a clean install of Win11. I was under the impression from them they'd backup everything on a new "backup" drive they installed to double my capacity as part of the upgrade process.

They're version of backing up Thunderbird left me with a folder "Thunderbird_profile_backup.zip" that is 9,698,657kb in size.

I am attempting to install Thunderbird on the essentially new computer and restore all data from the previous installation.

Is this even possible anymore at this point?

I have data in that file that is important not only financially but archived family info from now deceased members... I'd really like to recover it.

In short help! lol.

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 repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.
