Thunderbird Community Forum

I have been dealing with this issue for the last several thunderbird versions. I am currently running 115.18.0

Everytime I try to configure an existing gmail account for thunderbird via File -> New -> Existing email account

I specify my Name and gmail email address, then password for the gmail account.

The google authentication pop up launches " Mozilla Thunderbird wants to access you Gmail" and I click "Allow"

As soon as I click "Allow" I am asked to download a file.

Google gemini says this file is a sign that Oauth is not being accepted by thunderbird.

What I have tried. I verified Thunderbird is set to accept cookies I have verified there are no previously stored gmail passwords (as this has never worked) I have changed my default browser from Firefox to Brave and verified the same behavior

please help, Thunderbird has never been able to connect to gmail when running on this Ubtuntu install.

I am so annoyed, MS clearly sabotage this to push people back to their horrific software! I am so against that idea I lost an entire full work day today trying to do something SO simple, to install Thunderbird (for a friend) and connect it to MS365 email address.

It's IMAP, it should have taken SECONDS! It did create it, pulled in tons of email, but refuses to SEND any! I tried every single suggestion I could find online, going back years. NOTHING works! All i get every time whne sending email is : "Login to server smtp.office365.com failed. "

Does anyone have a magic cure, 6 solid hours of this and I still refuse to give up hopes of making Thunderbird the active mail client! Thanks

When I reconcile my checking account each month, it's handy to be able to search my e-mail for the amounts of transactions that I can't identify by name alone. Gmail allowed me to do this. Thunderbird, for some reason, doesn't. Anytime I search for a numerical value (e.g., "36" or "9.58"), Thunderbird returns no results. Why are numeric strings not searchable? Is anyone working on this deficiency?

I started getting this problem about 6 months ago. I have used Thunderbird on Linux for years with very few problems until about 6 months ago. What happens is that when I send a message I get a dialog box saying sending and it will hang there for a long time, sometimes permanently. The size of message doesnt matter. Sometimes I can click on cancel and then retry and I am sometimes told it was sent but not saved. Sometimes it did not get sent at all. It is getting more and more annoying. It seems to happen after long periods of inactivity. Its not DNS, I have changed settings and DNS servers make no difference. I even went through and deleted lots of email and still it persists. I am running no extensions.

I have just acquired a replacement PC and installed Thunderbird, and (as happened on previous occasions) I am unable to send emails because the outgoing server settings that were automatically detected are incorrect, and even feeding in those I recorded on the last occasion does not work. I have had a long conversation with somebody at Plusnet Help Desk, who agrees that the outgoing server should be mail.care4free.net and the port number should be 25, and the connection type should be SSL. He also thought that on my "Account settings" screen there should be an option "Account actions" through which I may be able to solve the problem, but this is not there. I think that last time I had this problem, some genius on this forum managed to solve it, and hope that this will again be the case!

Thunderbird (current version) freezes each time an email is closed and when it does so, it freezes the entire computer. Computer: MacBook Pro 16"; Tahoe 26.2. The freeze last for 2-5 seconds before it releases.

lost emails from thunderbird working thunderbird this afternoon & it jus just wiped out all my emails every one it even deleted some local folders is there any way of recovering these emails thanks for any help

Suppose I see 10 incoming emails on my server (core.com). In thunderbird, when I click to download them, I see a message saying something like "downlaoding 10 emails". After that only 2 or 3 of them have been downloaded, the rest deleted. Help! This started happening a couple of weeks ago. I have tried downloading and re-installing Thunderbird, to no avail. Should I change my account settings?

Bonjour, Ma femme, victime d'un hameçonnage, a effacé le mail frauduleux que réclame l'assurance Allyatys. J'ai pu récupéré tous les mails effacés ( plus de 800) en employant la méthode de X-Mozilla-Statuts: 0000. Mais bizarrement ce mail frauduleux manque à l'appel dans la période indiquée. Pouvez vous me dire qu'elles en seraient les raisons ? Par avance merci pour vos réponses. JL

Updated Thunderbird and lost all my local folders and address lists. I imported CSV addresses to new version and can view them but when I go to use them in an email they do not show up. How do I access them?

Hi there, Just installed Thunderbird email. Before uninstalling Outlook 2016, I tried to forward some messages to Thunderbird, but Thunderbird will not show emabedded images or attached photos, regardless of format (JPG, WEBP or PNG) Example: Instead of the image embedded in the email, I got this: g:20260201194950ee722ec300f042669bef9585ca10p0eu&R=1KSFSC960P76L&T=O&U=https %3A%2F%2Fimages-eu.ssl-images-amazon.com%2Fimages%2FG%2F01%2Fnav%2Ftransp.gi f&H=8QFJAA9HOQ1LXLAKNXLPWFHXGSSA&ref_=pe_109088481_1104238771_opens>

I have Original HTML in Thunderbird settings, not changed anything. How do I resolve this? I appreciate your help

My contacts address book is provided by Apple iCloud, of which I have added contacts with avatars for every contact I've received legitimate emails from. However, Thunderbird fails to render these avatars. The result looks like the attachment. Perhaps Apple is using HEIC for them?

I have Thunderbird with the same email box on my computer, laptop (both Windows 11) and mobile phone. Starting this morning, any new messages stopped coming to the laptop and computer, only to my Android mobile phone. I have checked all the email settings but there is nothing wrong

Hi, With new version 1.143 all accounts are gone, need to re-create my existing mails accoutns (outlook, yahoo, gmail) but all fail on error message "www.mozilla.org uses an invalid security certificate" How to resolve ? Grtz, Jane

Update: Apologies, seems it was my mistake. While setting up the signature in the first place I *did* pick up a named anchor from a template <a name="_MailAutoSig">. It was buried in the generated HTML, and I have now found and removed it. Problem, such as it was, now solved.

Is there any way either to remove the yellow anchor symbol which Thunderbird inserts in front of my signature, or to tell the client not to display the symbol? I didn't put one in the HTML signature that I use. There's no "remove named anchor" command. It isn't related to the double -- marker, which I've already removed using config. I have no use for anchors, which for me are simply a visual distraction.

Thunderbird is so good in many ways (calendar synch is great - one of my major bugbears with Outlook - also recipient privacy when sending out group invitations) and it can be quite frustrating in some others (e.g. unwanted features that I've had to dig around in config in order to turn off)

Thanks everyone :-)

Hi there,

Is there a way to get checkboxes to select messages or at least a plan to get it in a future release? I saw that there has been an add-on in the past, but not maintained for some years and therefore not possible to use in newer versions. Yes, I know that you can select messages with ctrl and mouse click, but there are others in my family who are not familiar with it and reluctant to get used to it. (have used gmail for too long).

Greetings Grauer
