Thunderbird Support Forum

Whenever I open my Thunderbird email application .. its constantly asking me to re enter all the passwords for the email accounts I have within the app .. I even select to save the password but its constantly asking me to enter it than i enter it and a minute later again it loses sync with the server and i have to re enter it again and again for each email I have linked within the app

I received the new version, Version 115.10.1, and the next morning I have emails going to other folders, 1261 junk files that had already been received over maybe the past week or so all received again AND not filtered to the junk folder but rather to the inbox. 2 emails moved from inbox to another folder. Train wreck.

I am using Thunderbird 115.10.1 on Windows 11. T keeps deleting my saved passwords. T takes a very long time to load. There are no saved passwords and I enter them all with the options to save. I check the passwords in Settings and they are all there correctly. When I next run Thunderbird it may or may not have them still saved. I check the Settings and they have gone; so I enter them again and they are saved OK. But then they are deleted some time later. I cannot see any pattern in the failure. I wonder if there is a problem with the outgoing server setttings. All the passwords are lost whether imap, pop (Ionos), hotmail or yahoo. Is there a way to clear out my profile or is this a problem with this T release. it did not happen until about 1-2 months ago. My profile is on a local NAS. Generally T seems to be quite unstable ; I get Not Responding too often.. Thanks

I get this message from Thunderbird on my desktop computer on app start up: ]Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

This started suddenly about a week ago.

I have Thunderbird on laptop that works fine.

How can fix this?

Other than just the setup, how do I get Thunderbird to use "POP" rather than "IMAP" protocol for email? Until March of this year, I had Thunderbird setup as a "POP" client for email downloads from Frontier. And, then Frontier moved all of their email services to Yahoo and in the process, my Thunderbird wound up using "imap.mail.yahoo.com" instead of "pop3.frontier.com". I don't want IMAP - I want POP. So, I tried changing that in Thunderbird setup to "pop.mail.yahoo.com", but it does not respond.

Posted this before, got no answers, not even a "no, there's no cure for that." Hoping for better this time.... My inbox suffers from disappearing email sometimes, and using the properties>repair cure works okay as far as I can tell (if someone emails me and doesn't ask about it later, how would I know?). But it has happened frequently enough, half a dozen times a month or more, that I do the repair by default pretty much every day just to be safe. That's easy but still a pain. Does nobody in MozillaWorld know a more permanent solution to free me from my constant missed mail paranoia? As I said, a reasonably authoritative "No, there isn't" is perfectly fine and much better than radio silence. Regards!

Hello, I hope that this question is taken at face value. I Have tried working with the new UI since it was pushed and as of today I have had enough and I have reverted back to 102. there are a number of issues that have still not been addressed or fixed in 115 or 125 but the thing I keep finding increasingly infuriating is the UI. I understand UI is personal taste for some however for productivity changing the UI can be disastrous. it has been months since the release of 115. And the amount of time I have wasted because of the new UI is staggering. it is (to me and from what I am reading MANY others) extremely un-intuitive and tedious to use. I will not mention all the performance issues here as they are a separate issue. I would have liked to see an option to use the previous (read standard / tried and true) UI but since they did not, they appear to need an incentive to do such, so as the subject asks how much will it cost to add an option to revert the UI and how can we annotate that we would like it reverted as the donation page does not allow for notes or requests, and obviously the current leadership has a vision that is not in line with many users expectations.

I would like to reiterate this is not an attack on people who do like the new UI but a simple fact that many people appear to not like it and would like to be able to continue using the software both up to date and with a UI that actually makes sense to them since email clients have been virtually the same for over 2 decades now and that look and feel has become the de-facto standard in the industry for a reason.

TLDR: new UI is no longer intuitive to "industry standard" applications and I want to know how much it will cost to bring that back.

I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

Hello. I have a new MacBook M2. Thunderbird ver. 115.10.01 (64-x). Very high consumption of memory and energy resources of the laptop. The email client simply eats up the battery! I didn't install any add-ons. Everything is out of the box. Reinstallation didn't help. What is the problem and what should I do?

Thunderbird keeps asking for my password and password manager doesn't remember it. Each time I try to look at or respond to messages, it asks for my password --- I check the password manager box to remember it but it doesn't.

Should I delete thunderbird and then install a 2020 version where this was not a problem or is there a way to solve the problem with the latest current version

Peace, Alan

Yesterday I downloaded Thunderbird to Windows 10 (64-bit), added my Office 365 (for work or school) account, rocketmail account and iCloud account. I created unified folders for the three accounts. I have downloaded the TBSync add-on with the required CavDev (?) one to connect my iCloud calendar.

After successful use the first few times, now Thunderbird becomes unresponsive within 5 seconds of opening, every time, rendering the program unusable.

Troubleshooting mode does not fix the problem, so I assume it's not the add-ons, nor does starting my PC in Safe Mode (F4 at startup ie no networking), so I assume it's not antivirus.

I uninstalled Thunderbird and re-installed from the website today. All my accounts were there (so I wonder if the uninstall didn't work properly, although I assume that it's just the files left on my computer that the new Thunderbird installation is accessing).

All these attempted fixes leave the problem unchanged: the window freezing within seconds of opening.

Because the program becomes listed as 'not responding' and greys out on further clicks, I have to hard-close the program using Windows, selecting 'Close the progam'. Clicking 'Wait for the program to respond' leaves the screen greyed out, and nothing changes for at least 20 minutes (the maximum I've tried waiting it out). This also means that it does not yield a formal crash report, because Thunderbird does not recognise it has crashed.

On one occasion it did create a crash report, which I submitted. I am not sure what behaviour allowed this to happen, and I have been unable to reproduce it. That particular crash ID was as follows:

Crash ID: bp-41096385-eebe-4ccc-a47e-f76300240417

Any help much appreciated! I'd love to stick with Thunderbird if possible.

TB no longer will start. It just hangs and when I go to it on my Mac I see a spinning disk. That never changes and eventually, after hours, I must force quit and report it to Apple. I receive no messages or error codes.

Yesterday, whenever I tried to open Thunderbird I got a This app will not open on your PC Windows error, and Word and Excel would not work. Apparently I had some Windows 10 problems which I was able to repair with Windows Resource Protection. Thunderbird now runs, but all 2000 of my Inbox messages do not appear. If I open my Mail folder in my Profile, I see the four folders inbound.att.net, inbound.att-1.net, inbound.att-2.net, and inbound.att-3.net The size of each of these inbound Mail folders is 5MB, 9.8GB, 38MB and 20MB. So, all of the missing Inbox emails are in the inbound.att-1.net folder but they don't show up. I tried deleting the .msf file. That didn't help.

Does anyone have any suggestions?

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

Hi! I'm looking for emails in Thunderbird that contain "team energy". Why I get search results which have only "team" or "energy" in their text? How can I search for Mails including "team energie"? For the programmer: Why I get "results" with only one of this words? Why I get "results" with false words ("energy" instead of "energie"? Kind regards and happy search results Hans-Jürgen Dammann

I lost power to my PC when Thunderbird was running (thanks electrician who tripped the whole fusebox!). Since then despite everything I have tried Thunderbird will not open my mailbox. I get the screen 'Set Up Your Existing Email Address' shown in the screenshot. I can see my address book.

I have tried creating a new profile, copying across all the data from the profile in use until yesterday and changing the profiles.ini to point to the new profile. If I start using the profile manager (thunderbird -p) it shows the new profile but if I click it then I still get the same screen shown in the screenshot.

After looking at other support pages I tried deleting the .lock files and rebooting, still the same.

Under the troubleshooting information I can see the correct profile folder and open it, if I click about::profiles then the correct profile is in use.

It is a bit more complicated as I had the profile on a NAS drive but I have created a new profile on the PC and copied all the data in the profile directory to the local profile folder. Still the same results.

Edited: After trying a couple of other things - import into a new profile from the currant one, still same results, and changing the installs.ini file to match the profiles.ini one, also same results, I have uploaded a couple more pictures after looking again at other support questions.

I am on version 115.10.1 (32-bit)

Thanks for any help.

I have several email addresses all on my own website and all with identical setup at the server end. I just added two new ones to TB and they vanish when TB restarts. I've installed them a couple of times, they auto install perfectly, but they keep vanishing.

I've checked that all the mail servers and ports etc are the same as on the ones that work OK. So I'm assuming that the problem is some kind of generic problem with cache / profile corruption etc etc. Assuming that is the case, what kind of generic cleanup fixes should I try please?

Many thanks.
