Hi,

I would like to install Thunderbird in current version (135.0.1) via flatpak. My OS is Ubuntu 24.04.2.

Currently, I have installed Thunderbird version 128.7.1esr via flatpak. I was not able to change the branch from stable to release. Can you give me some advice?

Cheers,

Kai

Thunderbird Problem: For many years I have been using the Thunderbird mail client currently in ver. 128.7.0esr (32 bit) on S.O. Windows 10 Home Update 22H2 (OS Build 19045.5487), 64-bit operating system, x64-based processor. I have a couple of mail accounts, one of mine and one of my wife. My problem is that for a few days now (about 5 or 6 days) on the InBox folder of my account, only mine, I have not been able to compact the folder. When I try to compact it, the response message is always the following: <The Inbox folder on "my_account_name@gmail.com" cannot be compacted because it is not possible to write to it. Verify that you have enough disk space and have write privileges, then try again> On my disk the available space is 121 Gb on C: where the program with the InBox folders resides and 266 Gb where the data stored in custom folders resides. The write privileges are always the same, never changed, of Administrator. I have already tried the path of "repairing the folder" and re-indexing the folder, but without success. Can someone suggest a remedy, please? Thanks Riccardo ITALIANO Da molti anni uso il client di posta Thunderbird attualmente in ver. 128.7.0esr (32 bit) su S.O. Windows 10 Home Agg. 22H2 (Build sistema operativo 19045.5487), Sistema operativo a 64 bit, processore basato su x64. Ho un paio di account di posta, uno mio e uno di mia moglie. Il mio problema è che da qualche giorno in qua (circa 5 o 6 giorni) sulla cartella InBox del mio account, solo del mio, non riesco ad eseguire la compattazione della cartella. Al tentativo di compattarla il messaggio di risposta è sempre il seguente: <La cartella Posta in arrivo su "nome_mio_account@gmail,com" non può essere compattata in quanto non è possibile scriverci. Verificare di avere spazio su disco sufficiente e avere privilegi di scrittura, quindi riprovare> Sul mio disco lo spazio disponibile è di 121 Gb su C: dove risiede il programma con le cartelle InBox e di 266 Gb dove risiedono i dati archiviati in cartelle personalizzate. I privilegi di scrittura sono sempre quelli, mai cambiati, di Amministratore. Ho già tentato la strada della "riparazione della cartella" e della re-indicizzazione della cartella, ma senza successo. Qualcuno può suggerirmi un rimedio, per favore? Grazie Riccardo

Hi!

So we use thunderbird in the board of out student association and I was chosen as the board member responsible for culture this year. The previous person responsible for this has deleted/logged out of the ”culture” email. Now neither of us can log in, even though the password and other settings are most likely correct. What should I do? I feel like the problem is the fact that there is no name connected to the account at the moment, but I am not sure.

Thanks in advance!

Dear all I helped a friend from moving from Windows to Linux. He used Thunderbird under Win and so I collected all servernames and account data from his three mail-accounts. What I did not mention and what he did not tell me is, that he -over the last 10 years always moved important mails out of his mailboxes and stored them in the so called "local folder" (in German "Lokale Ordner" at the end of the left window.

Of course he was shocked when he mentioned that those content was not there any longer.. after starting Linux for the first time (and after setting up his mailboxes)

Now, the good thing is, that there is a backup from last October. (made by his 16 years old son - he copied the complete thunderbird folder in the filesystem ... and did not use any internal backup-mechanisms) Can I use this "backup" to restore the "local folders" ? - if those local files are stored in this backup - and if yes, how I could retrieve them

I have a "tree-file" showing the complete structure of the thunderbird folder... tree.txt... But I am not allowed to upload it here, as there are only images allowed.

I kindly ask you for help. As mentioned we are talking about 10 years mails frommy friend... Andof course I helped him for free to move from Windows to Linux.

Yours Karl

I donated to Thunderbird, I deleted and reinstalled Thunderbird, on a Ubunto 24.04 distro. but none of my emails are received by Thunderbird. They are in the service provider's inbox, but not Thunderbird. Do you know why, if your system confirms proper configuration I do not receive my emails?

Hello Community Members:

I seem to be having issues with Thunderbird. I’ve been using Thunderbird for years with no problems. A few weeks ago, I started getting a Not Responding notice when checking mail. I have a number of accounts to check. The Not Responding notice would disappear after a few seconds and the mail checking continued. Along with this issue, several of my folders would disappear only to reappear after Thunderbird was closed and then restarted. Today, all of the folders in one of my accounts disappeared and never reappeared. That account had 15-20 folders. I may have lost important correspondence. Does anyone know what’s going on and how to fix it?

Thanks for any assistance.

I am new to Thunderbird. I have gotten fed up with Kmail in KDE for Linux, it is basically useless since it does not allow any of the modern login protocols required by MS and Google.

One thing Kmail did do, was start in the background so it was always periodically checking for mail and indicating new messages in the icon and notification in the desktop toolbar. So you didn't have to have it running in the foreground as a running application.

How can you do that with Thunderbird? I tried an experiment by closing Thunderbird down and sending emails to accounts I have setup but no notifications appeared until I restarted the app in the foreground.

Thanks

I understand how to resize the panels and arrange the view, but how do you expand the overall main window that contains everything to give you more landscape to expand the panels within the window?

Thanks. It may be in here, but I couldn't find it easily.

Following a switch off and restart triggered I think by a Windows update, Thunderbird is not displaying any messages in my Inbox, though it is showing the number of messages in the Inbox title bar. 'Drafts' and 'Sent' all display correctly, but the 'Inbox' is blank with a grey icon of an envelope and the statement: "No message found". I am an IT novice. I looked on the 'help' pages. I have checked that no filters are set. I have right-clicked on the 'Inbox' title to display the menu with 'properties' at the bottom. I have clicked on that to bring up the dialog box with the "Repair" icon. It shows 'Inbox' in the 'Name' box but I note that the 'Location' box is blank. Presumably it should not be. Presumably it should show either the location of locally stored messages on my hard drive, or the location of the messages on the email server. I am not sure which. I have found the directory on my hard drive where I believe the messages are stored locally. The size of the file suggests to me that they are all there. The periodic 'Checking for new messages' is happening, but nothing is displaying, though a check via webmail shows that new messages are arriving on the server. What should I do to get my Inbox to display correctly? With many thanks, Iain

I have been a Thunderbird user forever. LOVE it !!! I used to have 2 email accounts underneath Thunderbird: TWC mail and Gmail. Every account worked great sending/receiving up until Feb 12. Then my TWC mail stopped replicating. Gmail account still works. Called TWC and was informed that I had to update my Master Password for my Spectrum Account. Worked with Tech Support to get me all re-established. Went into Thunderbird and still couldn't replicate. Found an answer dated 1/26/25 by teknikal at 10:44 on this Forum which sounded like exactly my problem. Called Spectrum every day trying to find the Server Engineer who could help me reset my password to no avail. Then i investigated updating my new password in the saved password of the account setting. There was only a saved password for TWC for SMTP which I updated and was able to successfully send and email from TWC to Gmail under Thunderbird. But I still can not receive emails and there is NO saved password for IMAP. So I did further reading and found my only alternative was to delete TWC from Thunderbird and re-add the account. Which I tried to do. But the configuration that replicated was mobile.charter.net which I manually changed to mail.twc.com but Thunderbird keeps telling me it can't find the server. I just got off the phone with Spectrum and my config is accurate: smtp mail.twc.com 587 starttls normal password chrismcm@twcny.rr.com imap mail.twc.com 993 starttls normal password chrismcm@twcny.rr.com Why isn't Thunderbird configuring my mail server so that I can send and receive emails ??? And now have I lost all my mail and folders since I deleted my account only to re-add it ??? I'm ready for the looney bin because I have been at this for DAYS !!! Please HELP !!! Thank you.

I am trying to set up Thunderbird and I get a message "Configuration found in Mozilla ISP database". When I click done, I get "Unable to log in at server. Probably wrong configuration username or password" HELP! Prefer a phone call.

I am trying to whitelist a domain name. TB won't let me do that. This company has a plethora of emails. I don't want to whitelist every single one of them. That would take me days. It is impractical. I want to whitelist the domain name which is concentrix.com. I want to ensure that all emails coming from that domain name land on the inbox folder. How can I do that on TB?

Hi there,

I am worried about privacy and security issues regarding to addons with very few users and reviews. I was hoping you could shed light on them for example Hawk (Like ChatGPT in your emails).

Are there any ways to guarantee my security and my emails not being seen?

For years I had a search folder at the top of my folder pane. I forget where it was exactly but it was no more than 3rd from the top, possibly under "Inbox". Today it somehow disappeared. So I've re-created the search folder, but now it's in alphabetical position, which puts it near the bottom. I know I can rename it with something like "aaa" to move it up, but is there another way? I tried marking it as a Favorite, but the Favorite Folder pane just appears at the bottom - so no help. I'm using v. 128.7.1 esr 64 bit.

I’ve got a minor but annoying Quick Filter button issue which just cropped up today out of nowhere, and haven’t been able to find an exact match for all these symptoms in any other problem reports.

Toggling my Quick Filter button works as expected, picking up the individual active filter buttons. However, in some instances of launching TB its on/off status indicator always displays as active regardless of individual filter button status. Weirder still, in other cases it always displays as inactive. It’s an intermittent problem, which always persists in one way or the other.

Further details:

- Problem is also present in safe mode, with the single plugin I use (CardBook) disabled.

- General display settings are “Theme Simple” and “Variant Normal” (not “Dark”).

- There are no automatic filters configured in “Tools > Message Filters”.

- Individual filter buttons are all working properly, including correct status indicators.

- Running current TB version (128.7.0esr 64-bit) on Windows 10 with all OS patches up to date.

An example:

Image 1: “Show only unread messages” button is active, and the Quick Filter button also displays as such (both indicators are correct).

Image 2: All individual filter buttons are inactive, yet the Quick Filter button still indicates a filter is active.

I’m stumped, thanks in advance for any help!
