Thunderbird Community Forum

Every time Thunderbird is launched, a new tab opens with a donation offer. This kind of persistence discourages not only donations, but also the use of Thunderbird. How can I disable this?

Hi, I'm trying to import all my emails from Outlook 2019 (5GB) on Windows 10 in KVM , TB 137.0.1 During the import process starts to hang / freeze after having imported about 1.4GB. When I check the task manager for activity, there is non. I.e. CPU activity is very low (where it should be about 80 - 100%) and no disk activiy is going on for about 30 min. I close Thunderbird, but I can't reopen TB. It says it's already open. So I kill the tb process. Then I re-open TB and it has about 1.4GB of e-mail imported. crash reports bp-2189a8c5-f639-4dd2-abfb-257f10250408 bp-34687354-02bc-4ebe-90fc-855d20250408

Is there something that can be done to fix the issue?

Thanks & Regards, Hermann

My most recent update is VERY difficult to understand and use. Is there any other way to ask for help with the endless really simple puzzles that this new TBird brings. I don't get any answers in this forum - or there may be answers but I can't find them. Where do users go to get quick how-to-do-it answers?

Hi,

In the vertical view, the extreme right hand should be the message pane. But in my vertical view suddenly the message pane is getting divided in half horizontally from the middle.

The upper half is been taken by the webpage, and the lower half by the message display.

Ideally the whole right half use to come as message display.

Please help with solution.

Hi,

I've been trying to get to the bottom of an error message that keeps coming up on my client's computer. They first noticed the error (ss) about a couple of weeks ago and anything from then won't download (incoming), but I believe they are able to send emails. I can see that the messages are 'waiting' on the server at least and they can temporarily use Webmail.

I looked through the forums and any other info I could find and have checked or tried the following:

• If their Antivirus or Firewall are blocking access
• There is enough space on their system
• File permissions for the 'Thunderbird' folder
• Access details
• Downgrading to an earlier version of Thunderbird

Unfortunately the error is still coming up each time they try to get their messages.

They have been using Thunderbird for almost a year now with one minor issue in that time. And I'm a bit puzzled as to what to try next. Has something similar happened to anyone else? Any suggestions for what I can do or check next?

The email account is through their domain and hosting and they are using Windows 8 and Thunderbird version 102.15.1 (from version 115.18.0 - 32-bit).

Thanks

I am running Thunderbird 115.18.0 (64-bit) on Linux Mint 21.3 Virginia (base: Ubuntu 22.04 jammy). My goal is to create an offline copy of a 13 GB gmail account in local folders and then delete all the custom IMAP folders to regain some free space in gmail storage.

I am achieving this by: 1) Setting up an IMAP account in Thunderbird for the gmail account. 2) Enabling local storage of all folders (in Settings and set config flag, etc). Changed gmail settings to unlimit the number of IMAP downloads. Set Thunderbird account concurrent connections to 15 (gmail max). a) Edit/Preferences/Advanced/General/Config Editor: mail.server.default.check_all_folders_for_new = true 3) Click on each IMAP folder in Thunderbird to initiate download of that folder. I don't see this documented anywhere but it doesn't seem to download the messages in each folder until I do this. 4) Turn Thunderbird offline and ask it to download all emails before going offline. 5) Copy all folders from the gmail account in thunderbird to local storage. 6) Turn Thunderbird back online. 6) Delete custom IMAP folders in Thunderbird gmail account to clean up gmail online storage.

In my mind, step 2 should be enough to force a download of all emails in all IMAP folders. I added steps 3 and 4 because it's unclear when this process is complete. Especially given gmail IMAP bandwidth limits: https://support.google.com/a/answer/1071518?hl=en

My questions relates to step 3 and 4. In step 3, I don't really have any way to know when Thunderbird has finished downloading all emails from all the gmail IMAP folders. I'm experiencing the typical gmail login issues and throttling due to too many concurrent connections and given this it could take days if Thunderbird can even keep track of which messages downloaded and which got errors back from gmail.

How do I know when Thunderbird has finished downloading messages prior to going offline? Does it notify me with a dialog or do I just have to keep hovering over the Offline toggle periodically until it actually says offline?

Any constructive tips on how to confirm everything is downloaded or process improvements, etc.

Thanks, pi

Opened Thunderbird today April 7, 2025 and the oldest email was from 2:58 PM April 6 2025. All my extensive collection of folders and old email have disappeared. New messages arrive in my inbox just fine. I suspect that there is a folder still on my hard drive somewhere with all the info in it. It appears that Thunderbird just can't find it for some reason. How can I help Thunderbird get back to using that file?

Thunderbird not displaying all new emails in the inbox. New emals are downloaded and visible in all other folders.

Problem started 2 days ago.

Checking on my cellphone using Google chrome on my webmail account new emails are shown.

If I quit Thunderbird and restart the new emails now show in the inbox.

What needs to be done to get All new emails showing up in my Thunderbird Inbox?

Good day! I'm using version 137. How do I sort messages from fresh to old (from top to bottom), and not the other way around? My correspondence can be very long, and it takes a long time to find what I need. Previously, this could be fixed with plugins, but now they don't work.

In the Thunderbird windows menu list, below minimize and zoom, the message subject line is lost (says "Mozilla Thunderbird" only) for incoming messages, but not for replies. Where can I fix this? --- Using Thunderbird Desktop Version 128.8.1esr on MacBook Air M2 with MacOS Monterey 12.5

I have 3 emails under a custom domain that i purchased through porkbun. I don't know the terminology but I am also using microsoft 365 as a domain? I purchased www.traditionsmeatco.com domain through porkbun but have emails through microsoft 365 cole@traditionsmeatco.com and domonique@traditionsmeatco.com and support@traditionsmeatco.com.

Anyways, I also have a gmail account, cole.minnis@gmail.com, this email works properly receiving and sending.

It's the other three that are giving me and issue and the warning i am getting is saying check authorization method in outgoing server. I will attach the screen shot of the alert.

I messed with all the options on the authorization method and nothing works!

Please let me know what to do, I hate outlook and now I am having issues here. I also changed password but no that didnt fix it.

I RECENTLY DISCOVERED (BY ACCIDENT) EMAILS THAT WERE SENT TO ME (AND I TOLD THE SENDER WERE NEVER REC'D) WERE SITTING IN MY LOCAL FOLDERS/INBOX. I CANNOT HAVE MY REC'D EMAILS GOING THERE. IS THERE A SETTING TO MAKE ALL INCOMING EMAILS GO ONLY' TO MY "EMAIL ADDRESS"/INBOX?

When I click on Thunderbird I get a popup box saying: Thunderbird failed to read config file. Then I click OK and the popup box goes away and Thunderbird loads as normal. How do I ensure that Thunderbird read the config file? Thunderbirds are go!!!

When I installed Thunderbird on my new computer, it immediately downloaded 3,900 emails from Yahoo (It serves my ATT.com email account.) The process took several hours and I could not stop it.

My email folder on my old computer is located at: c:\emailtb1 where I have about 100 folders (I make a new folder after about 100 emails.) I tried to change my location for emails to my old location without any success. Thunderbird used to ask you for the location. Any location worked. Now, there is a complicated process re profiles, I think it is called. Why make it complicated when simple works? How can I change to c:\emailtb1 so I can view my old organized folders?

My old email screen shows the 100 folders including inbox, sent, trash, etc. on the left of my screen. Then I have four columns to the right for Subject, From, Recipient and Date. Clicking on the column headings allows me to sort, and I can add columns easily. The new screen on my new computer is an absolute mess. It is many times worse than what I used since at least 2007.

I have been using computers and email since 1984. I am so frustrated that I am looking for a better email program. Can anyone help?

I notice that pressing J highlights a 'scam status" logo appears on the same line as the message I want to send to Junk or Spam box. But highlighting the logo leaves me with another action which I assume is to sort by spam status and select all such messages and either delete them all or carry them to Spam. Is there a faster way to do this? Thank you Brian in Auckland, New Zealand

Had issues with Comcast emails. They were set up with POP settings. Was on the phone with Comcast and uninstalled 3 email addresses and reinstalled using IMAP settings. I did not delete the message data leaving that box unchecked. After about 1.5 hours on the phone with Comcast was able to get the reinstalled Comcast email addresses to pull all of the emails off Comcast website. But there are emails that are missing from each of the inbox and sent folders for each of the 3 Comcast email addresses.

I do an incremental weekly backup using Acronis True Image 2020 Home Edition. I see the folders in the path but since they were saved last Saturday under POP settings, the backups I will need to try to recover are in 3 of the Comcast folders in the "MAIL" folder and not "IMAPMAIL" folder which listed 6 folders from imap.comcast1.net through imapcomcast6.net.

What do I need to copy from the correct Comcast folder called "Profile" where the izpoojy7.default is? Within this izpoojy7.default is the folder mail.comcast-1.net which has 1 of the 3 Comcast email addresses I need to recover the inboxes and sent folder emails. Please see the attached photo of the contents of this mail.comcast-1.net folder.

Do I just copy the Inbox.mozmsgs as well as the Sent.mozmsgs files? Or do I also need to recover more of the files within the respective mail.comcast-1.net folder? Thank you for any assistance you can offer on this matter.

My wife and I both have PCs on a network using an unmanaged switch. We both use Thunderbird as our email client. We would like to merge our calendars. Is that possible?

Thank you for your help.

I'm running Thunderbird on Arch Linux. A few weeks ago the following problem appeared. When I start Thunderbird I can view my calendar as usual, and it is all in place. But once I click off the calendar back to email, any attempt to return to the calendar shows it blank until I restart Thunderbird. My various calendars are listed, but all appear empty, and Tasks are similarly empty. When on my email, the Tasks bar is still working.

I can see a similar question on the forum, to which the solution was to delete calendar add-ons. I have tbSync and its dependency installed; I tried deleting them (by moving the relevant folders out of .thunderbird and restarting) and this did not help. I have also tried reinstalling Thunderbird, which also did not help.
