Thunderbird Support Forum

As a longtime user and a regular subscriber to Mozilla, I can’t get access to Thunderbird. Reason is that I had to repair the hard drive and now I am locked out. I am unable to insert a master password because I never had one. Reason being that I have used Thunderbird for years and years before that was required. To say I am frustrated is an understatement. None of your automated advice has a remedy. Should I install a new version of Thunderbird and begin afresh? John Cotterell ( an Australian supporter of your project)

My Thunderbird has been working properly for about 30 years, but now refuses to open. Message received says 'Authentication failed'. This happens repeatedly (for at least 20-30 times) and appears to relate to my password. It suggests 'Retry' or 'Enter new password'. The 'Retry' repeats as before so I check the Saved Passwords and enter the one saved. I get the same message. I am using Version 115 and have been for some time.

Could this be related to a change of Profile? There must be a way to reset the password? I have checked all the settings and no errors appear, all settings confirmed.

I have thought about a Recovery Mode and seem to remember seeing a message that I do have that. I just don't know how to access it.

Hello all together,

i just reinstalled my whole pc, win10 64. I exported my profile including all possible data, the .zip was too big to import so i copied it into the profile folder, on my desktop, in another foldet etc. But i always get the error message shown in the picture. This is my only chance to have access to my (partly) old email accounts... that's why i followed all steps, but i cannot import everything. I REALLY need your help and would appreciate it A LOT.

Thank you in advance!

I recently changed ISP carriers (from Network Solutions to Intermedia). The transfer was slow but everything worked just fine. Then, a few weeks later, I received a notice from "ExQuilla" asking me to sign up & pay, which I did not do. Monday morning, my Thunderbird email was frozen. I was able to go to the ISP's online portal to access my email and still can but I prefer Thunderbird which I have been using for decades. Mozilla has always been free other than donations. Is ExQuilla a part of Mozilla? Tim J Email hidden for privacy reasons

Every time I open TB email on my laptop I get the following page, which then exists as long as I am on TB. I can work-around this page to send and receive email. Here is the top half of the page:

Mozilla Thunderbird Email wants to access your Google Account undefined jschoolnews@gmail.com This will allow Mozilla Thunderbird Email to: More info Read, compose, send, and permanently delete all your email from Gmail

I upgraded to 115.9.0 to get OAuth for some, but not all, accounts. Those on Gmail & Yahoo are OAuth. I have non-OAuth accounts on a Zimbra server, and on Panix.com.

It prompts for the first account's password. TBird then gobbles all available CPU on the machine, and stays there. If I wait long enough, it becomes usable again, but that may well be hours.

However, once it calms down, it works normally.

Intertwined with this is: TBird rejects the Zimbra passwords as I enter them. I retry and retry, and then they succeed. I know the passwords are correct; I've even typed them out, and then copy&pasted them in. I'm not sure about the Panix account, if its password works the first time or not.

I tried restarting in troubleshooting mode; it made no difference.

We have a ministry known as ECAM (it's an acronym).. How can I filter on subject lines without also getting every subject containing the word became?

im unable to progress further than this and it wont matter because im not interested in any email service that doesnt have at least and preferably more than 15gb storage like gmail. send reply to- [removed from support forum]

I have been struggling with this problem for about 6 months now and no-one I've asked has been able to help me. Even my computer guru failed me! I think it was after an update about last June when I started having this problem An nothing I've tried has had any effect. I had a Geek Squad guy on the phone with me for about 45 minutes to no effect. He said he'd never seen the problem before. I have business emails on that account so I don't want to risk losing them. Can anyone help me please? Christine

I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

I can't use Thunderbird any more. I open an email and I get 7 copies up across the top of the screen. Delete does not get rid of them, and I am up to over 50 at this point. Please contact me directly at [removed phone# from public support forum] when you have fixed this. For reasons I have just outlined, email is not a good way to communicate.

I assume that everyone else is experiencing this disaster.

After installing Thunderbird 115.10.0 (64bit) on a WIN 11 system yesterday program does not close fully. It will not restart unless I use Task Manager to delete what is running or else reboot system.

I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

top - left "get messages". either the button or on the account right click and get messages.

its been one or 2 days now that i press either and also on TWO DIFFERENT PC running win 10 and 115.9.0 version and nothing happens! doesnt get any messages. dont even get the Checking notification on the bottom left. auto message retrieve doesnt work either no matter the time period. its like i am clicking on empty space... a while after, just by itself, it starts downloading again.

Since applying update 115.10.0, Thunderbird will not close correctly and will not relaunch until task is ended in task Manager. This is true on a windows 7 PC and windows 10.

How do I go about fixing error message regarding Incoming Mail: UID Fetching Failed

I tried support page, but all threads archived. Not sure how to proceed? Be kind too as I'm also pretty old!

I see that there are 9 messages...Tried tools, checked account settings and couldn't find anything.

Your help would be greatly appreciated. Bad day. My sink is stopped up too!

April 15, 2024 Thunderbird is Insecure There is missing functionality issues

1. How to Disable the "SHOW PASSWORD" Button in Security Settings 2. Either implement with a Password Password option, only to show the Passwords or 3. Allow the ability to Disable the Button

back in 1916-18 the ability to disable the "SHOW PASSWORD" Button worked with with a variation of the following at that time user_pref("pref.privacy.disable_button.view_passwords", true); I believe I created and used chrome.css or chrome.js

At some point this functionality ceased to work.

Now, I have scoured the Net to figure out a Solution simply setting the value to True, gets reset by Thunderbird, TB does not save it. it always reverts back to False and the button remains available and does not disable

I have tried everything, adding it in user.js, settings.js, userChrome.js I put it in every directory, nothing seems to work

Do I have to Lock it? - How? confusing and disappointing.

Please provide a simple step by step Solution to the problem

Thank you
