I have not changed my email accounts or my Google & Microsoft usernames or passwords. A few days ago when I started Thunderbird, two Google pop-ups arrive reading "Mozilla Thunderbird Email wants to access your Google Account" demanding that I deny or allow it. Why might this be happening and how do I stop it? This does not occur with other email apps such as Outlook for Windows.

I've been using Thunderbird for several years now without any issues, and I currently have the latest version installed. I typically have multiple email accounts logged in. Recently, I tried adding a Gmail account, but it wouldn’t log in, showing the error: "Unable to log in at server. Probably wrong configuration, username, or password."

I’ve tried the usual fixes like closing and reopening Thunderbird, clearing cache files, and even searching online for solutions. Based on what I found, I’ve tried turning off VPN/antivirus, changing the default browser, clearing browser data, and, finally, uninstalling and reinstalling Thunderbird after removing all my email accounts.

Now, I’m unable to log in to any of my accounts, which were working fine before. Can anyone guide me on how to resolve this issue?

Thanks in advance!

MS changed authorization method and now it require protocol OAuth2. I've changed my account for two layers authorization and tried change Thunderbird configuration due https://support.mozilla.org/en-US/questions/new/thunderbird/form but it not works. I can't connect. I've no problems to connect with Outlook and standard mail app for Win2010 or using BlueMail on android. Ive Thunderbird v. 115.11.0 (32)

Can You help me? I'd prefere to stay with Thunderbird.

Hi, I had the idea to try Opera browser as I saw various videos about it. Firefox does slow me down at times even though it's what I have used for years.

Soon after, I defaulted back to using Firefox but the settings must have gotten changed. Everytime I wish to log in to any site, I have to type in my email again. The passwords usually are the old ones that show up.

With Amazon for instance. I must sign in and verify with codes sent to my mobile few times a day. I have searched for help online and gone through the cookies and history and privacy settings, turn this on or that off, don't do this and don't do that. Despite all that, the sites don't remember my email logins. If I go from voucher code to another site, it doesn't remember my credentials, so I don't get the deal or voucher. Amazon on my mobile works perfect but on my laptop, it's just a nightmare to have to sign in and verify each time. Outlook refuses to recognize my password most times and so it goes on.

If I cannot fix this asap, I will then have to remove Firefox as a browser altogether and find anything else that works! Please advise. Last time I reached out to Firefox, I never heard back! Fingers Crossed x

Recently many sites have (for reasons I cannot fathom) introduced a pre-login form: ie a form that requires a username to be entered before an password text box is provided. This seems to be a trend and it is incredibly annoying.

The issue I have is that FF does not recognise the page/form as a login page and therefore does not provide a list of usernames for the domain in question.

Any advice or help would be very much appreciated.

I had to change my Google password. Immediately after the change on sept 14th, I was and am still unable to send or receive mails, receiving the message : "Authentication failed when connecting to imap.gmail.com server". Giving my permission/consent to allow Mozilla accessing my Google account is useless, because it is repetetively asking me to give my password in " imap.gmail.com" . I don't know how to do that : in the settings, there is no place to write my password. Do you have a solution ? Many thanks

I did a clean Windows reinstall on my computer and I forgot Mozilla account password, so I asked a password reset. It went fine, but my bookmarks and password were not syncing. I thought sync server is slow or similar, but nothing happened after 2-3 hours.

I searched on Google and found that a password reset deletes everything.

Developers! Are you f*cking serious if you don't warn the users when they are doing password reset if that will delete everything?????? I f*cking can't believe that!

I lost hundreds of passwords and bookmarks. That is f*cking insane!

I have been trying to get my Comcast email configured for days with no luck. When I try to log in using my Comcast password I get a screen that shows "Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server. Reference #18.321c2e17.1727662977.283cff2b https://errors.edgesuite.net/18.321c2e17.1727662977.283cff2b. I have allowed access to third party apps on my Comcast account and I am able to access my email on the Comcast website with no problem. I saw something about disabling IPV6 but it said to go to Preferences or Options in the Settings menu. My version of Thunderbird (latest) doesn't have these menu options. I have tried various IMAP and SMTP Port settings I found on the internet and nothing works.

What are the settings for Comcast email in Thunderbird?

In Firefox, and Firefox only, in every version for the last several months, I have found it impossible to get Firefox to allow websites to "remember this device", even when I check that option. Every day I log in to a website, for example Tmobile, and I have to get a code emailed to me. I check "remember this device so you won't need a code next time", but the next time I log in, the same thing happens. Over and over with many sites. This does not happen with any other browser, except Firefox. How do I get Firefox to allow me to save my info? I really don't want to use Chrome, Safari, Brave, or Edge, but I do not have this problem with any of them. Only Firefox. And yes, I've checked my settings, and everything I can see says Firefox should be saving this info.

hello, My gmail account disconnected and I cannot log back in. A window opens when I try to load my mesages, but an error occurs everytime. Do you know where it comes from ? Screenshots down below thanks !

‘Trying to install T-bird in new computer and I forgot the password. And no, the password for Thunderbird is not in the saved passwords in settings’ for ‘Thunderbird’ (Mozilla).

Thanks RM

Hello,

I have several email addresses with Thunderbird. When I open Niels.Wichmann@gmx.de a password is requested which I no longer know. Under privacy and security => saved passwords there is no imap for the account, smtp exists. I can access the account with my app on my cell phone. How can I set a new password or how do I get the password? I can display all other passwords.

Regards N. Wichmann

I like using Firefox but it is increasingly becoming incompatible with more and more websites. There is nothing wrong with the websites, I can login using Google Chrome just fine. Firefox simply won't allow me to login to certain websites that I was able to access using Firefox before. Anyone know why this is happening?

Title is quite descriptive. A few hours ago I cleared all my cookies and cache and a while later the browser updated. Now, whenever I close Firefox it automatically logs me out of my Google accounts. This happens only with Google accounts, as I'm still logged into other accounts.

<Rant about how ridiculously hard it is to find where to change the password>

I had to change the email password for my Outlook account. Now I'm stuck because there doesn't appear to be any way to change an existing email account's password. It frankly would have taken me less time to delete the account and re-add it than I've spent trying to find where to update this. Screenshot shows where I think it should be but no go. Online help points to interface options that don't exist.

Thunderbird version 128.2.0esr (64-bit)

Successfully migrated to a new server on desk top and android phone. Same settings on a laptop results in repeating "login to server failed" with requests for password; and will not connect.

Thanks for pointing to a solution.

How can I get my Yahoo mail (with new password) to come in on Thunderbird? I finally got it on another computer, but it won't work on this one. I can't see how to change the pw on Thunderbird, if that's the problem.
