When i attempt to retrieve my email I get the following message at the top of my screen, "The certificate for POP3.pangia.biz expired of 8/13/26. How do I renew it? My email address is jahoagy@signalpeak.net. Thank you John Hoagland.

I have been trying to archive my 25 years of Yahoo mail before they delete most of it. I thought I had it done. Now I have had to start again. Did you know that setting Thunderbird to ISAM download all your emails will only get the first 10,000 of any folder with more than that in it? Yes indeed, so it seems. We have to set the yahoo download server to the 'export' server. prefix the existing name with 'export'.

I am locked out of my yahoo accounts now. And the attempts I made earlier to delete stuff to make room have deleted stuff that never got downloaded/archived because from a folder with more than 10,000. That's how it goes. Just thought I'd warn anyone who might be as unknowing as I was. I took advice to the contrary and believed it.

I want to copy my windows Thunderbird profile to Linux but my Profile Directory will not open when I press open directory. I downloaded Thunderbird from the Zorin app store, and it may be a flatpak or something – it won’t tell me now because I have already installed it – but I believe that could be a reason for the directory not opening. Is there a non-PC-literate way of finding out and fixing this?

when I try and add my microsoft outlook account, it redirects to a webpage, which after saying yes a few times with an already signed in session, redirects to localhost 44645. localhost 44645 notably does not seemingly direct to anything, and thunderbird does not change. clicking "continue" re opens the microsoft webpage How should i connect my outlook account? system details; ``` OS: Linux Mint 22.3 x86_64 Host: ThinkPad L14 Gen 2a Kernel: 6.14.0-37-generic Uptime: 7 hours, 40 mins Packages: 2177 (dpkg) Shell: bash 5.2.21 Resolution: 1920x1080 DE: Cinnamon 6.6.4 WM: Mutter (Muffin) WM Theme: Mint-Y-Dark-Aqua (Mint-Y) Theme: Mint-Y-Aqua [GTK2/3] Icons: Mint-Y-Sand [GTK2/3] Terminal: gnome-terminal CPU: AMD Ryzen 7 PRO 5850U with Radeon Graphics (16) @ 4.508GHz GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series Memory: 14803MiB ```

I was a satisfied user of the Thunderbird e-mail client. I especially enjoyed the ability to toggle into darkmode when browsing and reading my e-mail. The previous toggle I used to activate that feature is missing, and I cannot locate a work around to turn it back on. Any assistance would be greatly appreciated. Thanks

TB suddenly moves messages from inbox to trash automatically without any interaction. Search through the forrum shows that it has been asked for already, see https://support.mozilla.org/en-US/questions/1588804, similar postings can also be found with you search engine.

As described in other postings, the messages are moved from Inbox to trash. When moving them back manually from trash to inbox, they are moved to trash again immediately.

• it happens for the default account only,
• there're no filters at all in TB,
• junk detection is disabled,
• Settings->General Storage is all disabled,
• (account)->Settings->Server Settings has checked "move deleted messages to trash",
• (account)->Settings->Storage is all disabled,
• Inbox->Properties "Repair folder" does not help,
• Inbox->Properties "rules is set to "use account settings" (and greyd out "do not delete messages"),
• exactly same behaviour when starting TB in save mode,
• manually deleting all *.msf files (for inbox) does not help,
• manually deleting xulstore.json does not help,

Additional notes, which are not related to the problem, IMHO:

• IMAP on port 993,
• no other clients anywhere are connected to that account,
• TB configured for more than 10 accounts, more than 500 folders and sub-folders,
• host with > 16GB RAM, TB uses 3GB virt,
• problem observerd in older TB also, at least 13x.x

I'd be happy to debug/trace the problem if someone can give me detailled insructions how to start TB with debugging. Please feel free to ask for about:config settings as they are non-ambiguous and language independent ;-)

Thanks.

Hello, When I open Thunderbird, I get redirect on the browser to sign in into my Yahoo account. I enter my logins and a pop-up window opens and says that there is no application able to open whatever it wants to open. I already checked the forums concerning the Oauth2 login security for Yahoo, and tried several of the advices, but I always get stuck at the same stage. My operating system is Ubuntu 24.04.4 LTS Thunderbird version 153.0 Am I missing an application? Or is something wrong with my settings? Thanks for any support.

For a few days I'm having trouble with Asana mails (notification mails informing me about replies, comments, etc).

Clicking on the mail to view it freezes Thunderbird for a good 5 seconds while one CPU core spins at 100%. This only happens with Asana mails (or at least I haven't found any other problematic senders).

I guess it's a problem with validation or parsing of the mail's HTML content. But I don't know how to debug this.

I can't pinpoint exactly when it started happening, but it was around the time I've switched to the [new snap release track](https://support.mozilla.org/en-US/kb/channel-choices-thunderbird-snap-and-flatpak#w_snap-channel-changes-in-2026). But since this happens with Snap and Flatpak I think the culprit may be the 153.0 update.

Things I've tried:

• Clearing cache and msf files.
• Troubleshooting mode with add-ons disabled.
• Reinstallation. Creating new profile + importing old data.
• Switching from Snap to Flatpak
• Switching Message Body display to Plan Text or Simple HTML.
• Disabling HW acceleration.
• Checking console for suspicious output.

Anything I can do to create handle the problem or collect information for a proper bug report?

Not sure where to post a feature request, but I use a scheduling app (Playtime Scheduler) that consistently offers ics files with an empty LAST-MODIFIED field. So I have to manually edit the ics file every time before it can import into my calendar.

Would it be hard to make Thunderbird ignore an empty field like that and import anyway?

I have thunderbird installed on my PC, and my main email account is a gmail account. I download from gmail using POP protocol (SSL/TLS connection security, OAuth2 authentication). I have been using these settings for a long time (15 years?).

This afternoon, thunderbird stopped downloading my messages. No error messages : just "no new messages to download".

I can see (by logging directly into my gmail account using my browser) that there are new messages on the server. They're not spam or junk, and they're not getting downloaded into my (local) spam folder. They're not getting downloaded at all.

I still have room on the google server (it's about 87% full), and room on the hard drive on my computer (about 3 GB).

When choosing to edit a sent message as a 'new' message, placing the cursor at the beginning of the message and pressing <Enter> does not advance the text.

It used to.

Placing the cursor at any other location within the message WILL advance the text with <Enter>.

I CAN add text by typing, but the <Enter> key does nothing.

The intent of placing the cursor at the beginning of the message is to add a line to the previously sent email.

The chosen option of 'edit as new message' should work with <Enter> regardless of where the cursor is positioned.

Any chance of this being addressed?

Thanks.

I am using ThunderBird 153.0 ESR for Linux Mint mint-001 - 1.0

I have 3 computers. Two are running Windows, and one is running Linux. I was pleasantly surprised to find that Linux Mint has Thunderbird built in. I keep the two Windows computers in sync with a file compare program, "Beyond Compare" Are my local folders compatible between the two operating systems so I can sync my Linux Thunderbird local folders with the ones I have stored in Windows Thunderbird local files?

Are txt files stored the same in both NTFS and ext4 systems?

In the process of changing from Windows to Linux, I have entered the details of my email account and it is fine when I press re-test, but when I press done it is not fine anymore. The email is “freeuk.com” which is still active but Freeuk itself isn’t, but the service was taken over by Claranet with a “clara.net” setting, so I imagine that may be relevant. Any help (not too technical please) would be appreciated. Thanks.

How can one setup a sending email server with same address and username but different passwords?

When trying to setup 2 different accounts i find a thunderbird limitation using API email password which have same smtp server address and username and only differs in password.

Is there a workaround?

ThunderBird upgraded to v153.0. Since then EAS and TBSync have stopped working. Extension Manager have disabled them and report both are incompatible with TB v153.0.

The option to "Find an alternative add-on" for both fails to find an alternative version to work with TB v153.0

Are newer version of EAS and TBSynce imminent?

Na versão 153.0esr do Thunderbird, quando se clica na pasta com o botão direito do rato, o menu não apresenta a opção de adicionar pastas aos favoritos. Para além disso, quando se arrasta uma pasta para a área das Pastas favoritas do menu esquerdo, nada acontece.

Hi, I just installed Elementary OS on a Dell M6800. The OS runs well, and I have multiple email accounts, so I installed Thunderbird from the Elementary AppCenter. It showed up as a flatpak install, but I went ahead.

Now, in the past when I tried to replace the .default-release file with one from another machine and rename it with the new filename (which is what I've always done to transfer my multiple emails and address book),

I went to the usual place, which has always been /home/myusername/.thunderbird/whatever.default-release, but it wasn't there. Going to Help/Troubleshooting Information/about:profiles shows it there, but won't open it when clicked on.

The only place I could find it was in /home/myusername/.var/app/org.mozilla.thunderbird/cache/thunderbird. But when I replaced and renamed the .default-release file there, and then restarted the app, I still did not have my old data. How do I go about this with a flatpak installation? Thanks in advance.

Grouping emails is awesome. Also have the preview show a bunch of compressed email info when a group is selected. However if the group contains only one email nothing is previewn. Is this a bug or a feature?
