Hello! My husband making a new company online and we just set up the needed emails with domain connected. Thunderbird was installed on two different laptop and all the 5 email got configured on both laptop. We run several test on all to see if it is going all fine sending and receiving on both laptop In one of the laptop when sending emails from thunderbird to gmail with 4 email out of 5 has a problem and at gmail site ends in spam or in one instant does not even deliver. We run a test program but that showed all fine, however emails keep showing up in spam at gmail site. Where is the problem? At the host? or at Thunderbird or at Gmail? What should be done to fix it? Thank you very much any suggestions and help. Kind regards, Krisztina

Incoming e-mails do not always appear in the inbox when they arrive. They always do appear but there are often delays, sometimes of a few minutes, sometimes of several hours, and sometimes of many hours. At the end of the delay they always do appear, with the time at which they were sent indicated, even though that time is earlier than the time at which they appear in my inbox. I have sometimes sent e-mails to myself, as tests -- and these are also often delayed for five or ten minutes. I am not aware of any actions that I take that precipitates either the start or the end of the delay.

Hi, Win 10 Pro new installation. Dell Optiplex MBR type Bios.

I had saved a recent profile to an external drive in its own name (i.e. not the profiles folder)

After the new Win 10 installation, I downloaded a new copy of Thunderbird.

I then copied the saved profile into the new Profiles folder, selected it in Choose user profile and started Thunderbird.

Thunderbird opened but not with the saved (8+ Gb) profile, just one new email account and asking for passwords to other email accounts I used before, and no folders.

I went back into the profiles folder and renamed all other profiles "OLDxxx999, but still the same one new email account when I opened Thunderbird.

I desperately need the saved email folders - I don't mind loading all the email accounts again, just need my court case history folders.

How can I force Thunderbird to use the saved profile, or can I identify and individually load in the saved local folders?

Thank you for any guidance towards a solution.

My hosting service caused me problems and are no longer available I have changed to new host, simply changing only the settings to connect to new host, same imap, port settings but now locally stored messages are no longer visible, I know they are stored on my system under /home/jim/.thunderbird~ but is there a way to retrieve them?

Hi, I am feeling pretty stupid, as I have been using Thunderbird for years on my PC. Now, on my laptop I can't find where to compose a new email. The new email button is not anywhere to be found, and up until today there was something that I could click on to "create a new email" in the top RH corner, but that is gone as well.

HELP

thanks in advance Graeme

Until a few days ago, I had a little button at the top left of my Thunderbird window to get any new mail. Now it has disappeared. If I've made that happen, I've no idea how. Please can someone tell me how to put it back? Thanks.

Thunderbird 128.10.2esr (64-bit)R

Mac OS 13.6.9

Cannot insert underlined hyperlink nor clipart into email using version 138.0 64 bit

Thunderbird makes it so difficult to fix settings anymore.

The config editor is a mess and unbelievable to understand what options are available and how to use them for anything speicifc.

When I downloaded the Thunderbird app to my new laptop and opened it, it already had a fortnight's worth of recent messages in the Inbox, plus many of my Sent messages. However, the remainder of the Inbox, dating back to 2010, was not there, neither were my address books. Why didn't a clean copy of the app download so I can import my Profiles? In addition, my old laptop uses POP incoming, but the new laptop seems to be configured to IMAP. Is this a problem, and if so, which should I choose for the new laptop?

firstly, i'd like to say this isn't really about settings, well it sort of is, it's about layouts, but there's no heading for that. sorry!

i've just gone from version 102 to version 128. for my use of Thunderbird, nothing much seems to have changed, except some things are now harder. (such is progress!) i would like to see the columns in message lists as proper columns, with headers you can click on. so only one line per message, as it used to be, would suit me just fine. that way i can compare things in the list, which i would say is really important. you can change the sort, and easily see how it effects things.

does anyone know if is there any way to achieve this? i can't see anything in Settings or View. thanks so much.

Hello everyone,

I recently saw Mozilla announce that the Pocket service will be discontinued on July 8, 2025, entering an export-only mode, with user data permanently deleted after October 8, 2025.

I’m very concerned about its future. The shutdown of Pocket really hit hard, and it makes me worry: could Thunderbird face a similar fate? Especially now that Mozilla seems to be focusing its efforts more on Firefox and AI browser development, I’d like to ask the community and official team a few questions:

1. What is the current organizational structure around Thunderbird’s development and maintenance? I understand that since 2020, Thunderbird has been placed under MZLA Technologies—an independent, wholly‑owned subsidiary of the Mozilla Foundation—and is managed by the Thunderbird Council. Does this mean Thunderbird operates under a fundamentally different model from Pocket?

2. Is there any possibility of Thunderbird being discontinued, divested, or “down‑scaled” in the future? Does Mozilla have any plans to shrink Thunderbird or shift strategy in a way similar to Pocket?

3. What is Thunderbird’s planned roadmap and how are resources being allocated? From what I’ve seen, Thunderbird is undergoing UI redevelopment (Supernova), monthly releases, mobile client initiatives, and new Pro services like Thundermail, Appointment, and Send. Does this reflect Mozilla’s confidence in its future?

4. How can users and community members show support or express concerns? If we want to help ensure Thunderbird’s continued health and growth, what steps can we take to encourage Mozilla to allocate more resources?

I was searching for an email that I had just deleted and discovered that the Trash folder connected to my inbox was empty. The one connected to my Local folders, however, was not. I cannot find a setting that would instruct Thunderbird on how long to save emails in the Trash folder and am sure I did not accidentally change anything. Any idea how to fix this?

Hi, I have a problem with Thunderbird tabs. I have some emails open, but after some time these emails disappear and I am left with tabs without title or content, why?

Tag names can be changed via message > tag > manage tags. But how can I change the tag ID ?

Let's say for example, I want to change the tag ID "unreplied" to "needsreply".

steps:

1. in user.js: change user_pref("mailnews.tags.unreplied.tag", "unreplied"); to user_pref("mailnews.tags.needsreply.tag", "needsreply");


2. search&replace all instances of regexp ^X-Mozilla-Keys:[^\r\n]+unreplied in all .eml files


3. Some tags are not stored as "X-Mozilla-Keys" inside the .eml file but elsewhere ( https://forums.mozillazine.org/viewtopic.php?t=3123346 ) – I suppose in the .msf files. They are in Mork format. Can I run a search&replace on them or will that break them?

Are these 3 steps enough or is more needed ?

Whenever a new message is received, which should go to the Local Folders\Inbox, instead a previous email from 2 days ago is always shown. I have recreated new emply Inbox and Inbox.msf files, but to no effect. Any suggestions on how to fix this?

Hello Team Thunderbird You are doing a great job. I use thunderbird regularly.

Yours Sincerely

Hi all

I have my sent mail going into my Inbox be default, so that I can see entire threads in context. It's set that way in Copies & Folders in each of my email accounts. However, I frequently find sent emails in the Sent Mail folder.

Can anyone offer an idea of why, and how to fix it?

Thanks Edwin
