Hello. I am trying to add a new provider, which means adding a new account. When I click "Add new account" it takes me to a page that asks me to enter my existing account. Does this mean the currently running account or the new account?

I've been using Thunderbird for years at this point and it was fine, but then some time after the latest update I stopped getting new emails. I tried a bunch of random "solutions" I found on the internet and I don't remember exactly which one, but eventually I got the web portal to pop up, and it showed that I'm logged out of all my accounts (they all gmail, btw). Using this windows I was able to log back into one of them, but then it didn't popped up again to let me to log into others. For a day or so I was getting email from that one account I logged back into, but then again, suddenly, no new emails. I decided to just start over on a new profile and that's where things went from bad to worse. Now I can't even get past the initial logging process. It gives me "unable to log in at sever" over and over, no matter what I try. I tried a bunch of different config suggestions, I tried the old school way of getting a device password, I've checked if localhost was running something - it wasn't. I tried uninstalling and reinstalling, installing an older esr version (I'm on Win10, thought maybe that has something to do with it) - same thing. Unable to log in at server. I can switch back to my old profile that doesn't get any emails anymore, I've backed it up, but what's the point. Kinda feeling screwed on all fronts here.

Also, whoever is replying to people on reddit with "thunderbird employee" badge, ghosted me after one message. Great support /sarcasm.

Version: latest (whatever auto updated updated to) and 140.8.1esr OS: win10. Mail provider: gmail.

I tried to start Thunderbird and it would not open. There was a message that read, "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." After trying to fix it and nothing worked, I uninstalled and reinstalled Thunderbird. Now all of my contacts and data is gone. When I tried to use the import tool I selected import from another Thunderbird installation and I can't get past the continue button.

How do I recover all of my data and contacts/addresses?

with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

On my PC Thunderbirds sending/receiving mail says the mail server refused my connection. My laptop works fine. I have duplicated my laptops in/out specifications onto the PC but still nothing works. Spectrum says everything on their end is fine but can't vouch for roadrunner who is the rr in my mail address of ca.rr.com. All this started about 4 days ago. Any ideas on what to try next? Thanks.

I just had a support session and the tech was unable to solve the problem. We tried installing a new version of Thunderbird and importing the messages over from the default install and it just freezes up. He tried replacing account settings with the account settings from a previous version and that didn't work either. He suggested contacting Mozilla to see if there was a way to import messages from the frozen default to my new profile.

I set up a filter to move messages to the junk folder. If it's not from a .com, .net, or .org domain, move it. Here's how I set it up... If the "from" incoming message doesn't contain "any of the following" ".com" ".org" or ".net" move it to "junk". It moved .com and .org messages to junk anyway. What did I do wrong? There are too many TLDs to create a filter for all of them.

i go to chrome have no problem getting and keeping Facebook i have closed and enable the extensions removed some and it either does not work or takes for ever in the version of Facebook. . I keep checking if Facebook is down there are limited problems but i do not see the problems in Chrome. if this keeps up i will be going to chrome which i really do not want to

Hi

When Thunderbird is started maximized it overlap taskbar if is set to hide and taskbar won't show until Thunderbird is minimized and maximized. Another way is to press the Win key two times. Then the hided taskbar can be shown/use. The same thing happens to Firefox. Only when is first started. Then if Firefox is minimized and maximized, press Win key two times, press F11 two times then the hided taskbar show/hide normal.

It is a setting that can be changed to start Thunderbird and Firefox in full screen and do not overlap hided taskbar?

I am trying to add one of my Google email accounts to Thunderbird. It brings up the "Sign in with Google" window, which is normal. But instead of "Sign in to continue to Google...", it says "Sign in to continue to Mozilla Thunderbird Email". Which then generates an error: "Error 400. The server cannot process the request because it is malformed. It should not be retried. That’s all we know." I've not ever experienced this issue before; adding a Google account has always been super easy and straightforward.

Hi,

When I opened Firefox today, it asked me which profile I'd like to use. I named one Katy and then continued. Now, I can't see any of my bookmarks, none of my passwords are saved, none of my sites recognized. I've been using Firefox for years. Everything I have is saved there. I just want my old stuff back. I'm signed in on my account, but can't see another profile that I can choose. My phone still has all the passwords and bookmarks from before but I I can't see what profile I'm signed in under. Can anyone help?

Thank you!

Katy

Two days ago, I made my first post to these forums. Now I'm being spammed with "Congrats on your first forum reply!" emails from this website. I am getting a new one every hour and a half or so. There is no obvious thing to do in the email to stop this. How do I stop support.mozilla.org from spamming me?

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

I cannot find the menu item on my mobile device to sync my Firefox account. When I select "menu" it doesn't have that as an option; it only shows me other topics I have used Firefox to search.

As of yesterday my Firefox browser no longer displays some screens within Amazon Prime correctly. It displays what should be images as text, which is difficult to read, unlike Microsoft Edge, which displays the Amazon webpage correctly. I am running Windows 10 with a support extension through October 2026, so could it be an update from Microsoft Windows or Mozilla Firefox that has caused the problem. Thanks for your help.

Can get(POP3), but can not send emails to a newly created personal outlook.com account.

the following error occurs when trying to send mail: Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)

all my setting are correct per thunderbird and microsoft:

  (smtp-mail.outlook.com, port 587,  STARTTLS, OAUTH2, xxxxx@outlook.com)

thunderbird error log file contains the following: . . . mailnews.smtp: S: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox. Visit https://aka.ms/smtp_auth_disabled for more information. [CH5P220CA0005.NAMP220.PROD.OUTLOOK.COM 2026-02-28T23:29:21.878Z 08DE7703D4D1982A]

Based on my understanding its seems thunderbird is using SMTP AUTH instead of OAUTH2 as required for newer personal outlook.com accounts. Is my assessment correct? If so, is there a fix?

I was using Thunderbird Portable 136.0.1, from Portableapps.com . I then upgraded it to Thunderbird 146.0.1, by following Portableapp's instruction of installing the Portableapp 146 version to the same path of the old installation.

I then I added an Office365 Business email account to Thunderbird, but there was a problem with the SMTP configuration. I tried to change it, but then I found out that there's something wrong with my Account Settings for all accounts; they don't save the changes.

Let me explain: if I right click an account and choose "Settings", a new tab opens [image 1]. Whatever changes I make there, to "Account Name", "Your name", "Color", etc. don't get saved; as soon as I switch to another account and come back they are gone.

This also applies for "Edit outgoing server..." at the bottom. It always reverts to "Default server" and then every time I want to send an email I must change the default SMTP settings to the right settings of that specific account.

The "Delete" button for deleting the account also doesn't work, if I click it nothing happens.

Interestingly, if I switch to "Server settings" or "Copies and folders" the changes there do get saved and are displayed correctly for the different accounts.

What can I do to solve this? I already tried Troubleshooting Mode to no avail. I am currently trying to install Thunderbird Portableapp to a different folder, how can I then import all local folders and accounts to this new install?
