Using a new, clean install of Xubuntu 26.04, with thunderbird 140.10.2esr 64 bit, ubuntu snap build 1.0. In settings: play a sound when new message arrives, no sound is heard. When clicking "play" to test the sound, there is no sound. Also, if "use the following sound file" is checked, there is no sound when "play" is clicked. (I have tried various .wav and .mp3 files.) I have installed pipewire-alsa, but that didn't help. Any ideas?

I've noticed that if I attach a file to an outgoing message then use ctrl+enter to send the message, Thunderbird also opens the attachment. How can I prevent it from doing the latter?

I am running Thunderbird 140.9.1esr on openSUSE Tumbleweed.

For a long time now, Thunderbird often runs at high CPU (80-100% of one core), for several minutes at a time (5-10 minutes). This seems to happen many times every day, with no apparent cause from my end. (I just got back from Lunch, and the fan on my laptop was going crazy because of the high CPU.)

What can we do to identify and fix this issue?

Had a double disaster, both OS partially upgraded at same time due to space issues and had to wipe and install.

Ended up with a TB install in Ubuntu where 2025 emails are missing. (see image #1) Found out that my backup should have most of them. (see image #2)

How do I safely identify the 2025 mail content in my backup folder, and how do I safely copy them over to the existing set up?

I see that the 933 profile exists in both so most likely it should be one of the lower number profiles in backup I need.

Attached are images of folder content.

Many thanks in advance!

Tags summary display has disappeared.

I can search for tags, but the convenient "tags folder" is gone. Please help.

Tried in safe mode with add-ons and toolbars/controls disabled. Error console is empty when assigning or removing tags.

I am a long time Thunderbird user and set up a monthly donation. I no longer have access to that Email account and I need to stop the donation. The Donor portal won't work because it requires me to access my original email account.

I accidentally archived multiple messages today that I had deliberately kept in my inbox for attending to later. My archive folder is set to "All Mail" unfortunately. Can I sort the messages in All Mail by date archived? It will be a massive task for me to find them otherwise as the messages I want to retrieve are up to 2 years old

Hello,

I'm trying to create a calendar event with irregular recurrence. Not only is the starting time different, but also the duration. Since AFAIK this is not possible using the interface, I directly edited the .ics to this:

RDATE;VALUE=PERIOD:20260506T063000Z/20260506T130000Z,20260507T054500Z/20260507T110000Z

I then manually synced the calendar. The starting time is honored, the duration, however, is not. I found the entry in the .ics changed by Thunderbird to this:

RDATE:20260506T063000Z RDATE:20260507T054500Z

How can I get Thunderbird to honor the different durations?

Thanks

For the last 2 months I have been working to configure Thunderbird to fully replace my Gmail UI usage after their recent change to workspace options and using data to train gemini. When you deactivate those gmail features the first thing you lose are tabs for your Inbox, your Updates and your Promotions.

So far I have used tags, ThunderAI, Ollama and a locally hosted LLM to replicate the sorting of my inbox, but now I would like to be able to configure the Thunderbird UI to allow separate tabs in the menu bar for different folders, in this case Inbox, Updates and Promotions. With Inbox still being the gmail hosted main inbox and Updates and Promotions now being local folders stored in my local thunderbird installation.

Can the Thunderbird UI be configured to display folders as tabs as a default setting? I tried the "folder selection" button under customize on the toolbar but that just gives me a drop down, which is not what I want.

i can't seem to copy and paste so, here goes: what i see that i send Our Blended Rates: ≤ 100,000 5.14% 100,000 to 1,000,000 4.64%

Now when i send it---it looks like this

≤ to 100,0000 5.14% 100,000 to 1,000,000 4.64%

No longer aligned. Thank you

I have two Gmail accounts and one school account that uses Office 365. In the left panel where the inbox, drafts, etc. are, the Gmail accounts are listed in blue but the school account is listed in white. I can't see any reason for this difference in the accounts' settings. What does the difference indicate?

I have a shared family calendar and a private google account calendar that is separate. I tried importing some events from the family calendar to the private calendar. I created a .ics file, and started using the calendar import function in Thunderbird on my Ubuntu laptop. I found the file, selected it, and filtered for current and future events. I then clicked the confirm import button, and the screen changed to a view progress screen. This screen correctly shows the target account, the source file, the import type, and the number of events, so I think it's correctly set up. The progress bar shows "Importing... 0%", and there it appears to stall, consistently after several attempts. I saw another thread that talked about read-only calendars, but I don't see a setting, either at the Thunderbird level or at the calendar level that might be restrictive in that sense. Is there a preparatory step or a setting I'm overlooking?

I use Thunderbird 140.9.esr and happened to notice some strange behavior a few weeks ago: I have 5 email accounts, all of which I access via IMAP. Immediately upon syncing, some (not all) emails disappear from the inbox of the first account and appear in the inbox of the third account. When I then manually move the emails back to the correct inbox, they remain there permanently.

When I check the accounts via webmail, the emails have indeed been moved from one server to the other. At first, I thought it was a problem with my filters, but none of the filters were set up to move emails from one server to another. When I disable all filters, the problem persists. Could it be that I made a mistake in the account settings? However, the accounts have been set up for several years now, and I’ve been using Thunderbird for just as long. I didn’t notice this error in earlier versions.

There is an attachment with searchresults. This searchresult belong to an accountname with an emailadres of my own. But in the searchlist there is another To: address. Here it is Gospel Music Hoogeveen | Tineke

It should info@contras.nl

How did I get this and how do I get rid of this.

Support will be appreciated.

Since the last update , Tbird is either a default window occupying ~1/3 of the screen , or full screen. The horizontal divider between message list and messages works. resetting/changing font size didnt solve it neither did

changing toolkit.legacyUserProfileCustomizations.stylesheets from false to true

or creating a new profile

OS linux mint 22.3 Tbird 140.10.0esr
