Good afternoon

I have been struggling to find some messages specific to specific dates and spend an awful amount of time tryomh yo access the correct one.

The solution proposed is a bit unclear to me, as it refers to "future folders". I need to unthread all my messages. Is this possible?

Thanks

PS The only version number i could find was for Firefox. There does not seem to be one for Thunderbird.

Running Windows 11 Home and Tbird 153.4.0esr. Tbird configured with IMAP. I have many years worth of emails stored in my Tbird profile folder. Profile folder is 25 GB.

I want to delete the bodies of all emails in the profile folder but retain the subject lines to minimize the size of the profile folder (while keeping bodies of all emails on the server). Then I can retrieve any email from the server.

Anyone do this successfully without losing emails? Is there a step-by-step procedure for doing this on the Mozilla website? (Google is giving me an Ai answer but not a link to a Mozilla answer.)

Thunderbird did not work last summer so I switched to Daily working similar and fine. One day forwarded messages started to contain a huge list of mail-data (Authentication-Results, DKIM-Signature,..) instead of just time, date, topic, adress. How can I get rid of this? Thank you

Today firefox changes theme and startpage everytime i startup, i have tried resync theme and settings, and turn off sync, and try remove startcash, and tried falesafe start, still the same.. and now i saw that firefox color addon was enabled by startup also.. should have something to do with the new update? The problem seems to be solved, perhaps it was firefox color being enabled by startup..

Hi, I’m having an issue with the appearance of the right-hand side where my conversations are displayed. It looks like it has reverted to an older version of the interface. Sometimes it switches back to the newer, more modern design, but in this case it has stayed on the old layout.

How can I change it back to the newer, modern interface? I’ve already tried changing the theme and restarting several times, but the issue is still there.

Could you please help me fix this?

Thank you!

I used to be able to 'click' an email link,.. and the page would auto open in chrome,.. with a message at the top of the screen informing me this was happening. For some reason I must now use right button, and open in browser,.. in order to open the email link provided. s/w as follows:- Name Thunderbird Version 156.0 Build ID 20260915113124 Distribution ID ubuntu-snap-build User Agent Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:156.0) Gecko/20100101 Thunderbird/156.0 OS Linux 7.0.0-34-generic #34-Ubuntu SMP PREEMPT_DYNAMIC Wed Sep 2 14:29:37 UTC 2026 OS Theme Yaru-yellow / Adwaita Application Binary /snap/thunderbird/1259/usr/lib/thunderbird/thunderbird-bin

I have tried deleting the handler.json file but this does not fix or resolve the issue. My current Files & Attachments,.. has just a pdf entry,... set to preview in Thunderbird,.. and this duly open pdf's in a TB tab.

I have found the config editor settings,... for network.protocol-handler.external.http and network.protocol-handler.external.https and can verify they are set to true

But I still cannot just click on an email link,.. and have it open in my default browser.... Can anyone offer some options as to what i am doing looking where,.. wrong. Many Tx

Since our clocks/time went back one hour last weekend, Thunderbird for Mac is displaying the incorrect time. It displays the time as 1 hour ahead, effectively hasn't accepted the time change. The system time is correct, and Thunderbird is set to read system time. I have also tried changing it to "set manually" to our location, it makes no difference. Any assistance greatly appreciated.

I REALLY don't want to see prompts like this ... when FF upgrades to a newer release. I postponed clicking on adding this application since I really didn't know what it as going to do, or how to remove it once done. The little 'i' in the red circle did nothing. So - I finally clicked on it to make it go away. Not hat I call a very seamless upgrade.

Using Tbird many years, but suddenly my compose window changed to microscopic fixed font for all compositions. Cannot be changed (unless a trick known!) by any font controls I know. Rumor this happened at an update? Useless to send messages too small for anyone to read! What is fix?

Everything I've tried in a script from crontab -e:

xdg-open /home/ipc/Desktop/thunderbird.desktop /usr/bin/thunderbird -mail & xfce4-terminal --execute thunderbird --title=TBird --minimize

None of them work via script, but manually they all work in the terminal when typed in manually.

Really need to get this to run, because I'm using Thunderbird's filtering for email to move messages around into folders, so when I use my phone, tablet, laptop, the emails are in specific folders. But I want it to stop at 1am and restart at 7am, because I want the computer it is running on to do something between 1am and 7am that is CPU intensive.

The last update to 156.0.1 changed my inbox settings.

Previously when I would highlight an email in my inbox it would show it read and show a preview in the lower frame. Now the email stays in BOLD and there is no preview frame. Where do I change it my Inbox back like it was previously? How do I change the setting so that when I highlight an email in my inbox it shows read and shows a preview in a preview frame?

I have configured the message columns in the Message List pane for all the folders the way I want them. Unfortunately, Thunderbird frequently changes the columns in some, but not all, of the folders back to the default column configuration.

To temporarily fix this, I click on the column picker button in the folder that has the column configuration I want and select "Apply columns to > Folders and its children > " my top level folder. I also repeat this and select "Apply current view to > Folders and its children >" my top level folder. Sometimes this corrects the column organization in all my folders, but I usually have to repeat the above procedure multiple times to get the columns arranged the way I want them in ALL my folders. This lasts a few days before Thunderbird again returns the message columns in SOME of my folders to the default configuration. I then have to repeat the above procedure multiple times to get them the way I want, only to have to do this again in a few days.

How do I stop Thunderbird from making these changes, or how do I change the default column setting to the way I want it, not the way Thunderbird wants it?

This is not a new issue for me. I've been dealing with this for quite some time over many Thunderbird versions.

I use Thunderbird expluicitly because it is open source application not bound to any specific services. I am very dissapointed to find connection to "thundermail" build into application and WANT IT PHYSICALLY REMOVE from it.

I kindly ask to help in removing it from my copies of Thunderbird. Thank you.
