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.

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

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!

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?

Desktop Windows 11 Thunderbird 156.0.1

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.

I spend the last hour or so in sheer panic and doubting my sanitiy as an email I was just reading disappeared from every mailbox I have here (I have 8 mailboxes in Thunderbird) . Also for whatever reason search is missing from the title bar.

The email was "archived" by Thunderbird inthe "Local Folders" I never use local folders as local folders is silly in 2026 imo. I have my own mailserver which is perfectly save and backuped and stuf I don't need yet another location were mail can hide.

Anyway that was a bit of a rant. This would not have happend if this sille ¨Local Folders" didn´t exist at all. But I seem unable to get rid of it.

How do I remove ¨Local Folders" from Thunderbird?

Hi. I am finding the scroll bar to the right of Thunderbird's main window very narrow and hard to spot where the cursor is located. Does anyone know if it can be made large, please?

Dear Firefox Support Team,

We are evaluating the deployment of Mozilla Firefox Group Policy templates in our organization to support Microsoft Defender for Endpoint Network Protection.

Microsoft has advised us that, for custom URL/domain Indicators to work correctly in Firefox, we need to:

1. Download the Firefox policy templates from:

  https://github.com/mozilla/policy-templates/releases

2. Copy the files and folders under the Windows directory to:

  `C:\Windows\PolicyDefinitions`

3. Enable the **Disable Encrypted Client Hello** policy.

4. Configure the following preference to disable HTTP/3:

```json {

 "network.http.http3.enable": {
   "Value": false,
   "Status": "default"
 }

} ```

Microsoft referred us to Mozilla for clarification regarding the lifecycle, compatibility and rollback of the Firefox policy templates. Before deploying the configuration across our managed Windows devices, we would appreciate your guidance on the following questions.

1. Policy template update frequency

We noticed that new versions of the Firefox policy templates are released quite frequently.

• Is it necessary to deploy every new version of the policy templates?
• Should organizations establish a regular schedule for updating the ADMX/ADML files?
• Alternatively, should the templates only be updated when a required policy has changed or when the installed Firefox version requires a newer template?
• Is there a recommended method for matching a policy-template version with Firefox Release and Firefox ESR versions?
• Could an older policy-template version continue to be used if it already contains the required policies?

2. Different Firefox versions across endpoints

Our users may have different versions of Firefox or Firefox ESR installed.

If the same policy templates and settings are deployed to all managed Windows devices:

• What happens when an installed Firefox version does not support a setting included in the policy template?
• Will Firefox simply ignore an unsupported policy, or could it cause policy-processing errors or browser compatibility issues?
• Is there a minimum supported Firefox or Firefox ESR version for `DisableEncryptedClientHello` and the `network.http.http3.enable` preference?
• Do you recommend targeting the deployment according to the installed Firefox version?

3. Devices without Firefox installed

Some managed devices do not have Firefox installed.

• Is it safe to deploy the Firefox ADMX/ADML files and related registry-based policy settings to those devices?
• Will the files and settings remain inactive until Firefox is installed?
• Could deploying the templates or registry settings have any effect on Windows or other browsers?

4. Replacement of existing templates

When copying the files into `C:\Windows\PolicyDefinitions`, Windows may prompt us to replace existing Mozilla ADMX/ADML files.

• Is it safe to replace older versions with the latest released templates?
• Could replacement affect or remove existing Firefox Group Policy configurations?
• Should the existing files be backed up before replacement?
• Do we only need `mozilla.admx`, `firefox.admx` and the corresponding language-specific ADML files, or should every file and language folder in the Windows package be copied?

5. Rollback procedure

If the deployment causes an unexpected browser, compatibility or performance issue, what is Mozilla’s recommended rollback procedure?

Should we:

• Change **Disable Encrypted Client Hello** to *Not Configured* or *Disabled*;
• Remove or reverse the `network.http.http3.enable` preference;
• Remove the associated Firefox policy registry values;
• Restore the previous ADMX/ADML files; and/or
• Remove the current templates from `C:\Windows\PolicyDefinitions`?

Please clarify whether withdrawing the Group Policy assignment is sufficient to restore Firefox’s default ECH and HTTP/3 behavior, or whether endpoint-level cleanup is also required.

6. Recommended enterprise deployment approach

For a managed enterprise environment, would Mozilla recommend deploying these templates through:

• The Active Directory Group Policy Central Store;
• Local `C:\Windows\PolicyDefinitions`;
• Microsoft Intune ADMX ingestion;
• Direct registry-based policies; or
• Another supported method?

We would appreciate Mozilla’s official recommendation so that we can complete our internal risk assessment and prepare an appropriate deployment, maintenance and rollback plan.

Thank you for your assistance.

Best regards, Summer

When you go to the "Help and Support" section, a link for transferring data to another device appears. It clashes with the overall design and is annoying. Please remove it.

As we sunset the WP Forms that we’ve been using for Distribution List Changes, I need for everyone to update the link in your signature for Distribution List Changes. My signature doesn’t have that line because I email so many people beyond clients…

Your signatures of course do have a line that invites clients to click here in order to submit change requests for their distribution lists.

Moving forward – please use this link as the hyperlink within your signature.

Please confirm with me once done, and let me know if you have any questions.
