I have Win11, Thunderbird Windows MSIX packagethunderbird-MSIX - 1.0, and several accounts (The box below won't take anything past "Thunderbird Window.")

I'm looking for some way to make a different ring either for one of the accounts or for certain domains or for a subfolder -- any way that I'll know when something comes in from specific domains. The special ring(s) can be for each of the two domains or both of them. Can that be done?

I have logged into TinyURL.com MANY times using Firefox. Now, I get a Cloudflare Validation Error when trying to do so (see attached screenshot/snip).

This was done in Troubleshooting mode, but is the same in standard mode, though I have no extensions enabled. I've tried turning Protection Tracking off; no luck. - We use ZoneAlarm, but the Web Secure functions are all disabled. - I have the same issue on 2 PC's, one Windows 10 and the other Windows 11, 64-bit. - I'm on FF release 150.0.2 - 64-bit, and both Windows installs are fully updated and kept that way. - I've reached out to TinyURL in hopes of resolving the issue. They suggested many of the above steps but not resolved this issue. - HOWEVER, I've found that login via Google Chrome IS seamless - no issues.

What is it with Firefox that it's having issues with the Cloudflare "Human" check? I've checked the Cloudflare site; all conditions are good, and this very setup passed the "Turnstile" check.

FF is my #1 preferred browser, so please look into this. I see that others have posted similar issues over multiple years here (but a search of support articles didn't find one . . .)

Thanks,

How do I remove "add sitename"* from Search bar drop-down menu?

• sitename refers to whatever site you are on at the time

I have no use for this option and find it overly invasive. I have searched everywhere for solutions and have not found any that work. If it is not currently "removable", please make it so.

Thanks

I downloaded the version on the site but I can't get it to accept my password all I get each time is this at the top of the box

Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI]

Just how am I supposed to understand what that means. I would be grateful for any help you can give I've been using Thunderbird for over 25 years without any problems, I had to reinstall Windows and now I've got this problem.

Good afternoon

I have been struggling to find some messages specific to specific dates and spend an awful amount of time tryomh yo access the correct one.

The solution proposed is a bit unclear to me, as it refers to "future folders". I need to unthread all my messages. Is this possible?

Thanks

PS The only version number i could find was for Firefox. There does not seem to be one for Thunderbird.

This morning Thunderbird asked me to update which I duly did. Once done all messages started disappearing from inbox. Eventually I found them and moved them back to inbox only for it to happen again

Have now tried 3 times, same result, every single email from Inbox keeps being moved to deleted in Local Folders

All new emails that have come in since appear for a micro second in Inbox before being moved to Deleted

This is obviously not a great situation to put it mildly and as it has never happened before and started straight after this morning's update I can only assume that the update is to blame

Any help would be greatly appreciated

Starting today (September 3), ALL of my received emails are being put into the Spam folder instead of the Inbox.

FYI, I have been running Thunderbird (TB) for years and have not recently set up any new filters.

I'm currently running Thunderbird 64-bit version 155.0 under Windows 11 Home version 25H2. I am also running Bitdefender Total Security, but I have turned off its Antispam function, both under my usual Standard User account and the Admin account.

I have tried:

1. Going into TB Settings|Privacy & Security|Spam and clicking on "Reset Training Data." 2. After closing TB, I deleted the training.dat file in my TB profile folder and restarted TB. 3. Right-clicked on my Inbox and Spam folders and clicked on "Repair Folder." 4. Exited TB, copied my profile folder to an external HD, uninstalled TB and reinstalled TB after downloading from the official download site. 5. Rebooted my PC.

None of these approaches has worked to solve my problem.

Thanks for any help you can give.

I have what should be a pretty simple question. 1. I deleted my Tbird POP acct because it stopped working. 2. I reinstalled it. 3. My saved mail folders were gone. 4. Is it possible to get them back? 5. * This question is for someone other than David. 6. I just want to get my old saved folders back into my reinstalled account. 7. It's been about five days since this all took place. 8.The version I deleted was a the previous release.

Helping a friend with her HP-i3 PC running Windows 11 that I setup in March of 2025. It was a new PC purchased from BestBuy in March 2025.

I had to restore the image backup of her C drive that I did in March 2025 because of a Windows problem that I wasn't able to resolve. Now that problem is resolved but Tbird has the old profile folder without her new email contacts. (Unfortunately, I did not remember to use Tbird to save a backup of her profile folder before doing the restore.)

She has a recent image backup so I can extract Tbird's profile folder from that backup. What would be the correct procedure to replace the current profile folder with the one extracted from the recent backup?

(don't currently have access to her PC so don't know the version number of Tbird currently installed)

I have "Allow remote content in messages" turned off. However I receive many messages for which I wish to allow it for that message. I do so and it works fine.

What I would like to be able to do is to have TB learn the message senders for whom I have allowed remote content so I don't have to click it every time. Is this a feature that is available that I am missing, or is it just not possible?

If not possible, please advise as I will submit for an enhancement.

Greetings!

I have a few questions if you'd be willing to answer.

There have been some changes and new additions to the croatian dictionary (https://github.com/krunose/hunspell-hr) and as such, the Firefox dictionary could be updated.

Can you confirm that the dictionaries and language packs are separate additions and that the dictionaries are used for spellchecking? https://addons.mozilla.org/en-US/firefox/language-tools/

When is the spellcheck dictionary installed, only when the user installs it or when the user installs a language pack?

In addition, the croatian dictionary has not been active for the past eight years. Maintainer of the current hunspell-hr dictionary has said that person behind the croatian dictionary extension has not responded for several years. https://addons.mozilla.org/en-US/firefox/addon/croatian-dictionary/ https://github.com/akoncic/mozillacroatiandictionary

What are your suggestions how to handel the situation? There is already a fork of the extension that is used as a pull request but has not been merged for years. https://github.com/krunose/mozillacroatiandictionary

Thank you for your understanding.

Have a wonderful rest of the day.

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).

This problem happened after the September update. No changes to any message filters. I am not the only one having this problem. What changed in the update that could have caused this problem? I have had to delete the problem account from Thunderbird because every time I move the messages back to the Inbox in Outlook, Thunderbird would move them back to Delete.

Logged into Thunderbird this morning. On current version. Noticed that the local trash folder had emails in it. I have not changed any of the multiple account setting. Send some test emails fro 2 accounts and they ended up in the local folder trash. What has happened. I want this redirection to stop. What other demons have been created by the current update. HOW CAN i fix this problem?

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

Since the last (v155) update, TBird started putting all incoming email into one subfolder under my main inbox. I have several message filters that sort incoming mail into various folders. When I disabled the message filter associated with the folder in question, the email started coming into my inbox folder again. The message filter connected to that folder has not been changed in a while, and is a "match any of the following" rule with a number of specific from/contains/[text] entries. When I examined the filter closely, I found two rules where the [text] field was blank, which apparently was causing the problem, but as I said, I haven't changed the filter in a while - what recent change might have caused this? (Either adding empty fields or else considering [blank] to be equivalent to [any].)
