Thunderbird has been receiving emails on my PC from Bell Sympatico for years, then suddenly stopped in July 2026 without my changing any settings, and I have to go to the Bell server instead.

Hi I am an older person and have lost my profiles on thunderbird email - one is [redacted]@xtra.co.nz and the other is [redacted]@xtra.co.nz. We are in NZ and accidently deleted the Thunderbird profile and not the corrupted new profile I was setting up. Thank you. Gloria Sandbrook. I still have [redacted]@xtra.co.nz on my phone for communication. Cheers.

whilst all incoming emails are visible, many do not display their message header in the Inbox List. such as the one captured with a screen shot. Several have displayed in this manner over the last few days as can be seen.

Currently using TB 153.0, Win 11 on desktop PC.

In past versions there was a progress bar on right end of the status line, along bottom edge of the screen, that showed progress while TB was compacting folders. That bar hasn't been visible in last few updates.

When prompted today, I allowed TB to start compacting. I'd permanently deleted a really big bunch of old emails in last few days, so probably a lot of space that could be recovered. I kept waiting and waiting and waiting, but without the progress I had no idea if TB was busy or possibly frozen. So I just left it alone. When I came back and tried to manually start compacting, it immediately said "Done, 0K saved". So it had obviously done the compacting.

If it's an option, how do I enable that progress bar? If not currently available, please consider restoring it in future TB updates. I -for one- think it's a very useful feature.

THX!

I have a new (to me) Microsoft Surface pc with an ARM processor. After a very recent update to Windows 11,my entire Thunderbird installation has disappeared and I have been forced to use the Web to access my emails from Posteo.de Can you assist me please?

I use Thunderbird all the time as my email on a desktop PC.

For several emails, especially some from yesterday the Correspondent and the subject have  ?crossed?

For example: an email looked from the Correspondent list as if sent from my energy provider but the message was from a Garden Centre. It's not a one-off; another message looked like from a magazine but was a receipt for a purchase. They were not consecutive so it's not as if the list has 'slipped' by one or two. I think it's happened before but not as worrysome.

Is there a reason or solution please?

I'm now scared to delete unwanted emails without time consuming checking each one in detail.

Thank you for any advice/support/suggestions

After the crash this morning (19/9/26) I cannot receive or send emails but can access existing emails (open them as well) I spoke to Telstra & they tested my bigpond.net.au account & advised all working So must be Thunderbird. In dealing with Telstra I changed my password. I have tried the old passwod & the new password but error message comes up log in to "Telstra account [redacted] @bigpond.net.au (POP3) failed" as I cannot receive emails can I be contacted via [redacted] or [redacted] @gmail.com Hoping this can be fixed Thanks Peter Carson Cleveland, Queensland

/redacted phone# and emails from public community support forum.

I downloaded Thunderbird on my new Windows 11 laptop and began setup by entering my full name and email address ([redacted]@utexas.edu, operated by Gmail). The next screen asks for my "email account password." I entered my Google password that allows me to access my email at Gmail (https://mail.google.com/mail/u/0/#inbox). But "Authentication failed," and I am stuck! I cannot finish installing Thunderbird. I have used Thunderbird for many years on my prior laptop (Windows 10).

I have recently closed my yahoo mail account, removed all traces from Thunderbird, but when I start Thunderbird, after a few seconds, I get a Yahoo sign in screen over the top of Thunderbird

Hey Guys,

My Left click to open links from my emails has stopped working. I have to right click and select Open Link. I have tried everything, tried going through some of the config editor options i saw people mention for this issue and its all set to True already. There is no data besides PDF under the settings / attachments section. So cant change anything there. I tried a new profile, no go. I did a full uninstall and delete profile and started again, still same issue.

Left click to open links for everything else on my computer like firefox etc. Just cant open links through thunderbird. It used to work, it seems to have stopped around the same time as the latest update but i cant be sure about that. Only stopped working the last few days,

Hello people, I've just upgraded my Thinderbird because my inbox didn't load on opening the programme. I guess I have made a huge mistake somewhere in the process, because my whole archive has disappeared. I very much hope it still exists somewhere and that I will be able to restore it with your help. Thanking you in advance, Nele Ysebaert, Amsterdam

My TB installation got corrupted due to a hardware/disk issue. On restoring it from backup TB keeps trying to download all messages again. I know this is something to do with the popstate.dat file but I can't seem to stop it. What do I need to do?

Also, I had never noticed this before (because I never looked at the TB file system) but TB created multiple folders for the email account.pop.mail.yahoo-1.com up to pop.mail.yaho-4.com. Why does it do this and is there a way to get back to just one file? Is this something to do with TB crashing or what?

Is it using all of these files or just the latest and how do I know? All of these folders have a popstat.dat file and one has multiple following the popstat-1.dat etc.

I've no idea how to recover from this. Any help would be much appreciated.

I have posted another question about my corrupted TB profile and restoring it. Having done the restore and looked through the profile folder it is clear that this is full of old files that are no longer supported/needed.

Is there a utility that removes these old files?

I'm not sure if TB updates should remove them but it doesn't appear to have done so.

When I read https://kb.mozillazine.org/Files_and_folders_in_the_profile_-_Thunderbird it is clear that there are so many of these that doing it manually would be prone to error. That resource also says it does not know what some of the files actually do.

Is there a better resource that lists just the latest files maintained by Mozilla?

If I do a new export does it only export the files it needs? The last time I ran an export the resulting zip did not contain all the files from the TB installation but I have no idea why.

For the past several months the saved passwords, for my Comcast account, have had to be reset. When viewed the password vault still shows the old but correct password. It happens after a restart required for a Windows Update. I put in a dummy password, reboot, put the original password, reboot and I'm back and working as it was in the past.

Isn't password manager suppose to save the password until changed or deleted? It had in the past!

I reset my Windows 11 desktop OS. Now have two Trash folders in each email.

Cannot delete any Trash Folder.

Was does it do this?

Easiest way to fix this?

I use Thunderbird to access my Gmail accounts. Gmail is confirgured for IMAP and I am able to access all of my E-mail accounts ... so that is good.

However, I do have one issue: When I delete an E-mail in Thunderbird, it moves to the TRASH folder and I empty that daily. However, when I go to Gmail, I can see that they are STILL in "All Mail". If I access All Mail in Thunderbird and delete messages, they reappear.

The only way I am able to get rid of them for good is to access them in Gmail. If I don;t, the All MAil folders grow like crazy and messages thgat I deleted are still there .. some were several years old.

Question: Is there a way to set up Thunderbird so that when an E-mail is deleted in Thunderbird, that it takes it out of "All Mail"?

Hi,

I am having trouble deleting an email account in Thunderbird and hope you can help me resolve this issue.

When I click the "Delete" button, nothing happens. The "Set as Default" option is also unresponsive. I have already tried running Thunderbird as an administrator, but the problem persists.

Additionally, I tried setting up the account on my phone using QR codes, but it fails to load all my accounts. Out of 5 QR codes, Thunderbird only successfully scans 3, no matter what I try.

It seems like there might be a bug or corrupt profile data causing this, but I cannot locate the root cause. Could you please advise on how to fix this or manually remove the account?

Best regards,

Hello fellow Thunderbirds,

I have been using Thunderbird for years and had thousands of emails in quite a few folders, with a shit-tonne of filters etc. My emails were running pretty well. I only use two addresses, but the folders help manage everything.

I just got a new computer last week. Prior to switching over to the new computer I read through the 'Export your Thunderbird Profile' help page, and the 'Move Thunderbird data to a new computer' pages. I've tried to follow all the info there (with a glitch, explained below).

I am using a Windows system and have gone from Win10 to Win11.

I have the following data:

• Mozilla Maintenance Service (in Program Files (x86) ).
• Mozilla Thunderbird (in Program Files (x86) )
• Thunderbird (In Users/Username/AppData/Local/Thunderbird) (Contains 'profile' and 'updates'

I tried to swap the above data into the same spots on the new computer, but alas, it's not working. I *may*, however, have fucked it up myself...

So... When I got the new computer, I immediately downloaded Firefox, but, alas, I entered my email's details before closing it down. It did download a few off the server, but only a day's worth (before I realised I screwed up).

As soon as I realised I'd mucked up, I uninstalled Thunderbird and deleted the files on the new computer (you know how when you download it doesn't always remove all the stuff, so I tried to do this).

I reinstalled Thunderbird, but closed it prior to loading the email addresses on (as instructed). I then transferred all the above data into the corresponding file areas on the new computer. However, everytime I try to run the program it just goes to the standard open screen (with the popup that prompts you to enter your email addresses and details into it - see image, below, in case I'm not explaining it right).

Anyway, I'd appreciate any help you might be able to give me as I'm desperate to get my emails running again and have access to all the saved emails which were in my system. Kindly. Larysa.
