Thunderbird says password or settings are incorrect for iCloud mail. I have tried everything AI suggested. I use a custom domain on icloud and I have even tried using the underlying icloud address as login. Nothing works. The app password is newly generated and I tried it with and without hyphens.

Please help

every time I enter some words for a search the system blocks access with an "I'm Not A Robot" process. while I always get past this it is annoying and has only started happening in the last few days.

Ich habe Thunderbird auf meinem MacBook Air von Anfang 2015 geladen auf dem MacOS Monterrey läuft. Sobald ich einen eMail Account einrichten möchte stürzt Thunderbird ab. Was muss ich tun, um diese Abstürze zu vermeiden?

My profile did previously work with news.eternal-september.org, although I very rarely used NNTP. The last active use might have been as long as July or August 2023.

A few days ago I added news.gmane.io, it did not appear in the sidebar.

news.eternal-september.org:

• was originally in the sidebar, and responsive
• is not in the sidebar after removing then re-adding the account.

Can anyone reproduce this issue?

Environment

Thunderbird 140.0.1 (64-bit) on Kubuntu 25.10. Neither Flatpak nor Snap; my configured software sources include packages.mozilla.org/apt/ for deb.

/etc/apt/trusted.gpg.d/packages.mozilla.org.asc exists.

The profile was previously used on FreeBSD 15.0-CURRENT, if that's relevant.

Hello, When I open a message in Thunderbird (146.0.1 (64-Bit)) and then delete it, the tab should close afterwards. Can you tell me how to set this up? Kind regards Solveig Berends

I've been using Fire Fox for decades, but lately it is so slow, I thought there was something wrong with my Windows 7 ultimate. I've done full Windows reboot, to no avail. Then I see the internet t hat FireFox is starting to implement AI. I thought that may be the issue, but after looking into it, looks like that isn't an option with my old Win 7 OS. So if that isn't the problem, how can I find out what is bogging Fire Fox down? I keep a watch on my CPU usage, and the usage is going nearly to 100%, when it used to barely go over 10%. When I check the actual CPU usage, it shows as many as 15 or more items tied to Fire Fox.

Is this all a result of continued use of Win 7? I'm planning to move to Linux, but that will take me some serious time and effort. Gerald

Hi,

I use the Page Info window quite regularly, it used to be accessible via the right-click menu but this seems to have been removed in recent updates. I can still access it via Ctrl+I, but this isn't as convenient as using the menu.

Could you please tell me how I can put this useful feature onto the menu / toolbar as a shortcut?

Thanks

Owen.

Hello Our town had two unexpected electrical outages during severe thunderstorms a few days ago. When I reopened Firefox and tried to log on to my outlook account, I received the following message: UTC Date: 2026-01-10T07:45:12.961Z Client Id: 6ACCBE246D464180895379C1XXXXXXXXX Session Id: d6e32139-5adc-4e94-b1e6-ff2b299c8f50 Client Version: 20251212003.10 BootResult: 2152857611 Back Filled Errors: None err: NS_ERROR_FILE_CORRUPTED: esrc: Preboot et: ClientError estack: getItem@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:21149 i@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:7:141360 importExistingCache@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:23004 946909/i/<@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:7:151863 initialize@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:21016

I can open my email logins in Chrome and Safari, but not in Firefox. In Firefox I can open all my previous Bookmarks, but not Outlook. Any advice gratefully received, thank you

For some strange reason, I get this response when logging in to local newspaper on Firefox..image one. When loading the same newspaper on Edge, I see this instead...image two. I've been in contact with the newspaper but the techs there can't figure what's happening. Is there a setting I have wrong on Firefox? Thanks for your time.

I'm using the latest Thunderbird on Fedora 43, fully updated. Suddenly, Thunderbird is telling me that I have messages in my inbox, even though none show. If I receive an email, read it an delete it, the number of phantom messages increases. Compacting the inbox (or all mail boxes) has no effect on this. Any suggestions?

I have spent hours with Tech department and digital assistand department at Directv. Today they are telling me as long as I use Firefox I will be unable to access my account. I have paid to have my computer checked out and was told that it was updated and the system was working fine. How to I get Directv to recognize my system?

How does one take away many entries in Trash with one sweep instead of one by one? I was able to do this before my marking all of the items and then clicking CTRL and X, but that no longer works.

I'm experiencing problems across numerous sites using the above version of Firefox, detailed below. Other browsers are OK, as are other versions of Firefox on different devices.

Outlook365 email - "Your message can't be displayed right now" Fantasy Premier League - unable to log in, hitting 'Log in' doesn't respond Faceboook - content does not load Ebay - html on formatting in listings is screwed up Duckduckgo non-functional - returns the message "Ugh, it happened again! The server encountered an error and could not complete your request." The Guardian - images do not load Nextdoor - messages do not load

Have been trying to set up some pop3 yahoo mail accounts on a new computer. I have used automatic configuration. I have used manual configuration using the data from my old computer. I have checked the configuration settings on both Yahoo and Thunderbird sites. In all instances Thunderbird verifies the account is valid, but the next window asks for my yahoo username and password. I cannot get passed this stage. I have tried entering my yahoo password and I have also tried the app generated password from Yahoo, all I get is a Yahoo "something went wrong" message. Interestingly I did manage to get one of the accounts to work yesterday, but I must have tried no end of different permutations and I have no idea which one eventually worked.

Hello Thunderbird supporters

This is a problem, because some faulty emails land in the folder "Junk", others in the folder "Spam". It is NOT possible to re-change these folders in german language. I don't know what's the cause for this changement - I didn't use a new source for my Thunderbird.

Thank you very much for your efforts

Kind regards Peter
