I am unhappy with version 150 of Thunderbird. In earlier versions, I was able to access the full range of emojis when writing an email. That is no longer possible; I can now only access a few. The integration of add-ons with Thunderbird isn’t working properly. After adding the German dictionary, Thunderbird froze; after adding ImportExport Tools, Thunderbird not only crashed but also wouldn’t start up again.

Running Thunderbird 128.14.0esr (64-bit) via 64 bit Win11 Pro v. 25H2 on a Dell Inspiron 16 plus, Core i7-12700H @ 2.3 GHz, 24 MB cache, 40 Gb RAM, 877 Gb free on a 1.8 Tb Crucial T710 NVMe SSD drive. Integrated Intel Iris Xe graphics using 20 Gb shared RAM.

I have 5 email accounts (AOL = Yahoo, Yahoo, GMail, Verizon = Yahoo & MSN) each with a distinct IMAP server description. I also had my daughter's AOL account in the same TB profile.

On 5/9/2026, I foolishly entered my credentials in an AOL request for verification of her account (to allow TB access). As result, my jawarters@aol.com account and her jmwarters@aol.com account somehow became linked. Her email account in TB now contained only messages which were duplicated in my email account.

I deleted her existing jmwarters@aol.com mailbox and attempted to recreate it in Account Settings. Despite entering distinct IMAP settings (user name = jawarters@aol.com, imap.aol.com, port 993 and user name = jmwarters@aol.com, imap.aol.com, port 993) and having distinct SMTP settings with the user name in the Description, the recreated account again downloaded my emails into her TB account. The same happened when I opened TB on my desktop.

Interestingly, TB for Android v. 18 kept both accounts separate. I attach a copy of the TB Android k9s settings file which shows the same IMAP and SMTP settings as the laptop / desktop TB.

Help solve my self-imposed problem! Jim W

For some reason since reinstalling my Thunderbird every time I try to sen e-mail I get the error "Sending of the message failed. An error occurred while sending mail. The mail server responded: <SantoshS1@vbeyond.com>: Recipient address rejected: Access denied. Please check the message recipient "SantoshS1@vbeyond.com" and try again.

They are perfectly valid addresses, as they are generated using Reply. This did not happen before I was forced to reinstall from scratch. I suspect it may be some sort of issue with my account configuration in Thunderbird, as I had to recreate that.

I have moved my Thunderbird data from drive C:\xxx\Thunderbird to N:\xxx\Thunderbird. The Thunderbird program remains on "C:\Program Files\Mozilla Thunderbird" How do I tell Thunderbird to find its data on the N: drive?

Not sure what has happened to my PC but lost my Thunderbird app.

Reinstalled but cannot get my emails working again. I only get emails up to 13th May 2024; I guess when TSO Hosting finished?

I am now on 123 Hosting.

I have a note that SERVER for both i.e. Incoming and outgoing is:-

sxb1plzcpnl503269.prod.sxb1.secureserver.net (smtp as prefix)

Where and in what format do I enter theses server details.

I think I also need to get into cPanel but the URL I have will not work:-

https://sxb1plzcpnl503269.prod.sxb1.secureserver.net3 (:2083)

Sorry but I am confused; don't get old!

I just want Thunderbird to show remote images automatically without me clicking the button. Just show all images. The setting you ask me to change does not exist.

Everything has been fine for several years but this morning I now get error: TB could not connect to server mail.twc.com, the connection was refused. Spectrum says everything is good on their end. What do I have to do to "fix" Thunderbird? I can't send or receive any emails from 5 accounts with Spectrum and the emails are there when I log in at WebmailSpectrum.net..

I have been using Thunderbird for a very long time. Today is the first time I have seen this happen.

In the column on my left side that has my account and folders for those accounts it is showing 5 in my junk account. But in the preview window to the right of that column there is nothing showing as far as any entries as junk mail. It is completely blank. What do I need to do to clear this 5 from the left column Junk folder??

I have tried resetting the machine and that did not work. I even went into the webmail site for my email provider and there is no junk email showing there at all so as far as my email provider goes, it looks like everything is working there.

I can receive outlook e-mail but I cannot send from Thunderbird. I am asked for a password for the specific Microsoft server. I enter my Microsoft account password but this does not work. Security setting is STARTTLS withNormal Password authentification. My other Thunderbird non-MS e-mails are problem free.

I've been using Thunderbird for about two months now and I just realized that Thunderbird (150.0.1) seems to be unable (or unwilling) to use some of the fonts that are on the computer (Windows 10, plenty of RAM and disk space).

Let me explain that I don't send a lot of emails, and most of the ones I do send are just a few lines so I had not had any reason to bother with the font -- the default font was fine -- until today...

Today my experience with fonts in Thunderbird was extremely disappointing. It started when I was composing an email and I copied/pasted some text from a web page into the email. Rather than treating the pasted text as simply text to have in the default font, Thunderbird put it in some strange font and size. This might have been Thunderbird's attempt to use the font from the website but neither the font nor the size resembled the text that I had copied/pasted. That was when I noticed that Thunderbird does not let you choose the actual size but only offers the choice to make text larger or smaller. Making the text smaller was sufficient for that particular time.

As I finished the email, I tried to sign my usual signature. Thunderbird lets you choose the font but once I had chosen the font that I routinely use for my signature, I discovered that Thunderbird totally ignores the choice that it just let you make. Instead of displaying the signature in the chosen font, it displayed my signature in a plain sanserif font.

I could live with a limited choice of fonts -- I have used another program where the only choices were serif and sanserif -- but I cannot understand why Thunderbird would offer a font choice menu that includes all my installed fonts when it actually only honors three choices. The only fonts reliably used seem to be some generic sanserif font that Tunderbird calls Helvetica/Ariel, a generic serif font that it calls Times and another serif font it calls Courier.

The dropdown menu lets me choose any of the fonts I have installed, some of them display properly while composing the email, others don't. If I send the email to another of my email addresses, Thunderbird displays the text the same way -- some fonts are correct and some fonts get replaced with one of Thunderbird's generic fonts.

I'd really like to have all my fonts available -- but that doesn't seem to be possible with Thunderbird so I guess I need to figure out which fonts Thunderbird is willing to use.

1. There is not a relevant "topic" above for this question 2. How can I print a 1 page email on 1 piece of paper? View headers are set to Normal. I get one page with From, To, Reply to, & Subject then body on next page. I used to just select Print and my emails printed normally. I have been using Thunderbird for more than 20 years with out this problem

This is what I get when I click on email link. I can't delete it. This has to be solved before I can get to my second problem https://webmail.spectrum.net/mail? context_token=eyJza3NpZCI6ImNvbnRleHRfdG9rZW5fc2lnbl9rZXlzZXQiLCJza2lkIjoiNmJkYzZiMTEtZjBiZS00ZGFlLTliOWUtY2RkMGMyNWE5ZmUyXzIwMjAtMDEtMjRUMDcuNDIuNDQuMzQwWiIsInNlY3BvbCI6ImNvbnRleHRfdG9rZW4iLCJraWQiOiI2YmRjNmIxMS1mMGJlLTRkYWUtOWI5ZS1jZGQwYzI1YTlmZTJfMjAyMC0wMS0yNFQwNy40Mi40NC4zNDBaIiwia2V5VHlwZSI6IlJTQSIsImFsZyI6IlJTMjU2IiwianRpIjoiYWU2MzMwZDYtNTBlZi00Mjk3LThlOTMtZDUxOWVjZmMxMjdkIn0.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.SkxhnFtRLxHTpXXn5_kDX8nBISuPu3wdpoNFwTKLtmUadL29D40rNMHlmEOOa2LbGFVi8qlEWnscUMV8WXGLF02RFhSsEMFtBbXGpB9XUy6q_YW5FRJo1su5AJxboh1LMastJ39rdqnooQsnvA5_Mmy4NDBZrb1bQCmzXn3wiLsiBDMxorQ8Kk45CEWL6Bz09Z8EltuEQ2yVN3FGTGqAeU2i5-qNv12kzgimIu4TbDyE2DIi6_AKenLGc1kXlcZ8oxGjUEbJm1AThmpNbGF9WJ7d55_JQyfGWvEMIYNOtAiPaNNRCF1AlcBP3TAH34L1uI49Ve6C0SvidbRu2jYDuQ&referrerAppVisitId=202601311716P-753ab3c2-c22c-44cd-865d-2b77307fabfa&referrerAppName=SpecNet&referrerAppType=Web

Hi I am a theme girl and have tried many over time. I had never used the Dynamic Theme which is supposed to change from day to night along with what it's doing outside. It was kind of bland (sorry to the creator) so I tried to change it to another one and it worked just fine. When I came back to my computer it had changed back to the Dynamic one again. Again I changed it then it was back again. Yesterday I actually removed it from my list of addons and now it's back again. How do I stop it? Thanks for any help. ♥

Thanks

Moderator note: Moved to the Thunderbird Desktop forum from the Firefox Desktop forum.

The spacing of the Subject column label is inconsistent and apparently not under the control of a user. In the graphic with yellow notations, the leading space for Subject is much larger than any of the other column labels shown.

Also, in the graphic with red notations, the leading space for Subject is even larger; I "applied columns to ... Folder ..." yet both folders are not the same as the leading blank space for the Subject column header is different from the "copy from" folder.

I cannot find anywhere that this is controllable by the user. Please advise on both issues: too much space on the Subject column before the word Subject and the inconsistency of the Apply Columns To feature.

Thank you.

Recently, when reviewing my emails the correspondent is NOT correctly listed. It's another entry in my contacts with no connection to the email, which IS in my contacts. It's getting worse and worse, happening more frequently. The header info is correct within the email, but it doesn't display correctly in the correspondent field. Checked my email provider, and they are listed correctly there.

How do I get the correct correspondent to be listed for the corresponding email within thunderbird?
