Thunderbird Community Forum

The same question is from 2020. Today I had to reinstall but can't find a solution to switch to a readable light version. NOTE to developers. in SETTINGS is a section called "Language and Appearance." It should be here. The Dark Mode setting should be there - it would make hundreds of people happy.

Thanks for your help.

Failure to download email from Optus. I have spent a number oif hours to no avail talking and typing with the Optus staff regarding this problem. 1. I can send email from TB but cannot receive. 2. I can see the incoming emails in their Webmail site. 3. Optus confirm my settings are correct for both the mail server and SMTP server. When I go to Settings> Security > Passwords > remove server so I can re-submit my password, the only one showing is the SMTP server. Should the incoming mail server also be shown?

I am frustrated and ready to dump TB but have bee with it many years and don't want to start again with another programme as I am 83 and am partially blind. Please can anyone assist?

Hi all,

Filtering has always worked fine for me until recently. However, over the last few months I've noticed that any new filters I've setup don't work. Existing filters continue to work fine.

I've checked to see if there's an update but apparently I'm running the latest version: 128.11.1esr (32-bit)

Any ideas?

Thanks

when I try to run Thunderbird it opens with my folders but the comes up with the message "Login to server imap.gmail.com with username scoteng1961@gmail.com failed." I exported my details then used the thunderbird uninstall program. then reinstalled it. but problem persists. What password is it asking for and how can I get a reminder of it or a chance to change it?

I need to backup Tbird so that I can reset my PC, then reinstall Windows 11 and all applications. (There is malware that I and Tech Support have been unable to find.) I am familiar with the procedure for moving my profile to a new PC and have successfully executed it before. However, my installation is a little different. In addition to saving / restoring my profile, I also have to set the Local Folders parameter from the Account Settings menu, pointing the Local Directory to files on my HDD. I also seem to remember that the order that this is done relative to copying the profile matters, but I can't remember the details. Can someone help me out?

Hi, I have been using Thunderbird for many years. I have not made any changes to the standard Windows 10 version.

Suddenly, when I want to open a New Message, the button is highlighted in blue but nothing happens when I click on it.

I copied both local Thunderbird file and roaming Thunderbird file, removed everything and reloaded Thunderbird Eclipse. I still cannot access the account on Yahoo mail.

Hi: I need to import my data shown here: C:\Users\DonB\AppData\Roaming\Betterbird\t70e12zz.default\Mail\pop-mail.outlook.com so I see all my email and its folder structure.

I think Outlook.com became: outlook365.com?

Where do I change this stuff so it works?

As soon as I open Thunderbird, the program freezes before I can click on anything. The password prompt box appears, but regardless of whether I click “Cancel” or try to enter the password, the program freezes and only displays “No response.” I am unable to click on any menu item, as the program freezes even then. I wanted to repair it via Windows, but only the “Uninstall” tab appears in the Control Panel, not “Repair”... It doesn't matter whether I start Thunderbird in safe mode or normal mode. The problem is the same. Version: Thunderbird x64 de 140.0.1 Does anyone have any idea how I can access my emails, which I urgently need? Many thanks! Ekki

Hello Mozilla,

I have used Thunderbird for a long time but recently my contact with eBay has worked but i cannot access any choices they give me. Access with Chrome is great but I prefer Thunderbird so can someone please sort this problem.

Starting yesterday 4-3-2025 my Thunderbird email keeps locking up and saying it is not responding. I can close it and open it and then work with it for 2 or 3 minutes and it will start not responding again. This is a consistent problem the last few days. I did check and it said there was an automatic update on 4-2-25. I am not sure if this had anything to do with it but i did go in and request an update about 2 hours ago today. This has not helped as I still consistentaly get the not responding problem. Please advise what I can do to fix this.]

After updating to Thunderbird version 140.0esr, I am unable to create a new email. Clicking “Write” or “New Mail” does nothing – no compose window opens. However: • Receiving and replying to emails works normally • Safe Mode does not resolve the issue • Disabling all add-ons has no effect • Reinstalling Thunderbird did not help • I confirmed I am using version 140.0esr

Hi, Is it possible to change the Thunderbird folder pane (folderTree) appearance to look like the Thunderbird 102 style shown in your screenshot (smaller, more compact, and using simpler icons). Like imge below this

I using thunderbird version 115.10.1 and i try use CustomCSSforTb but it only change icon and colors. I cant change the tree folder style.

Hi =)

When I click "Write" and compose an email, the text I type is very, very small. I have tried all the settings in the font settings, etc. I can choose a larger font, but then the text becomes very large for the recipient as well. It can't be correct that the text should be so small, it is hard to read it, that small is it. This happened after reinstalling the new version of Thunderbird this evening. When the email is sent it is ok size. See enclosed pictures:

1) When writing -> Too small 2) In the inbox -> Ok size 3) Email is opened -> Ok size

I really hope someone can help! =)

Best regards, Margrethe

I asked about this in the past but have got nowhere. I haven't been able to use my Thunderbird account since Last November. I keep getting the message "Connection to server imap.iowtelecom.net timed out" I can get emails through the providers email but can't get them through Thunderbird. I have used Thunderbird for many many years. I can't figure out how to correct the issue. Wondering if I should try setting up a completely new email address with it but have had the old one for many years. Any help is appreciated. thanks!
