Thunderbird Community Forum

I am running Thunderbird version 115.4.1 on the Windows 11 system. Having Thunderbird active (even in the background or minimised) stops the Windows key from working. How can I get the Windows key to work normally without closing down and exiting Thunderbird?

I've read a few historic suggestions about how to resolve this, but I haven't been comfortable with what solutions were suggested as they didn't seem to comprehensively answer the questions, I'm afraid.

Until this morning's attempts to resolve the "running out of disk space" warnings, I had two mail accounts on Thunderbird - my old Hotmail account and my new personal domain based account. Both accounts had old emails (3/4 years' worth) filed locally on my PC pending my satisfaction that the new mail account was working satisfactorily. To try and resolve the storage issue, I deleted all the locally stored emails from my Hotmail account from within Thunderbird, then deleted the Hotmail account, and restarted both my PC and Thunderbird.

The expected reduction on space occupied by the .thunderbird folder didn't materialise - at all.

How can I get back the space so I can continue working, please?

TB 102.8.0.

Since December 2022, compacting is not working properly. I have set TB to ask me whether to compact when 100 MB would be saved. This has worked fine for years. Since December, I receive a pop-up advising that 237 MB or slightly more can be saved. After compacting, the message repeats every hour or two.

Compacting is actually, working except for the 237 MB chunk of data that either can't be compacted or doesn't really exist and fools TB into thinking compaction is needed. For example, if I set the compaction threshold to 500 MB then the mailbox will grow and I will eventually receive a reminder to compact when more than 500 MB can be saved. Compacting at that point does indeed shrink the mailbox. But, immediately thereafter, if I set the threshold back to 100 MB I get a message that 237 MB can be saved by compacting. Thus, the compact request repeats endlessly, all day long.

Technical details can be found here: https://bugzilla.mozilla.org/show_bug.cgi?id=1791354

I can't take it any more. Does anyone have a suggestion for forcing TB to re-examine or re-index my inbox in a manner that correctly determines its size and ends this nuisance?

Thanks.

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

Hi all Since 26/09/2023 I haven't been able to receive or send emails on my main dektop PC. At first when trying to download e-mails I got a "Secure Connection Failed" error. I was using version 115.15.1(?) It has since updated to version 115.3 and the error message hasn't re-appeared, although I still can't send or receive anything. When I try to send an email I get this message: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) relay.plus.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again. I have a laptop where I have copied all the account settings across to and that works perfectly. (on the same internet connection)

I am using Win 10 64 bit with Thunderbird 64 bit and Kaspersky IS, with Mozilla as an exception in the firewall settings.

I am a bit of a numpty with email programs, so have no idea where to start.

Regards Keith

This is a recent issue. If I send an email with no images and no attachments, it copies the email into my "sent" folder with no problem.

If I send an email with even a small attachment...it sends the email, but "times out" copying the message to the sent folder.

I've checked the account/server settings, they are exactly as recommended. I've changed the sent files to "other"...no difference. I deleted and reinstalled Thunderbird...no change.

Ideas?

Not used Thunderbird for about a week as was away. On my return I am now getting duplicate downloads every-time I open Thunderbird on my desktop using Windows 10. I am on Thunderbird version 115.12.2. I have been using Thunderbird for a long time and this is the first time this happened.

I recreated the global-message-db.sqlite indexfile, turned off my anti-virus, compacted folders but nothing solved the problem.

However I did find a similar question on this site with a solution which wasn't exactly the same but lead me to investigate the Mail folder in my profile. I see I am getting duplicate pop.gmail.com folders (pop.gmail.com, pop.gmail-1.com, pop.gmail-2.com, etc.). I guess that is probably connected to the problem.

When I open Thunderbird I also get the message 'Connection to server pop.gmail.com was reset'.

Any help would be appreciated. I didn't want to delete any pop.gmail.com folders without expert advice.

Thank-you in advance.

Thunderbird just updated to V115. But now, I no longer can see anything. Nor, can I navigate to anything since there is nothing there? How do I either fix this, or revert back to an earlier version that worked? See attached screenshot.

I've been unable to use Thunderbird since I had SSD fitted to my laptop. I have tried everything suggested on this site but to no avail. I have asked te question on here as well. It's a great shame, having used Thunderbird for a long time. I need an email client. Are there any others I can use?

I accidently powered off system (PC with Windows 10) without closing programs, including Thunderbird. After restarting the system and opening Thunderbird, TB crashed. I have tried numerous fixes:

• Installed the latest version of TB (from 78.11.0 to 102.8.0)
• Opening TB in Safe Mode (disabling all add-ons, reset toolbars & controls)
• Uninstall & reinstall TB

All result in the Crash Reporter dialog, with Report Contents. I can supply the report contents. (It wasn't obvious how to attach to this forum post.)

One KB item (https://support.mozilla.org/en-US/questions/1337785) suggested that the issue may have to do with session.json file. Based on the file timestamp, that seems likely. But I don't know how to edit this file to fix the problem.

I also created a new TB profile, with does not crash on startup, but I cannot get email properly configured.

I have hundreds (maybe 1000s) of email stored in TB that I cannot access.

I would greatly appreciate any help!

I use TB daily on my PC .. yesterday all fine. Today W10 booted OK, I started TB and it opens with a page asking me to create an account ..... seems to have no details of my inboxes, accounts or filed mail

Rebooted PC - restarted TB ... same again

I checked on my iPad and all 3 accounts still working so it is limited to TB on my PC

Seems to have lost my profile(s) How do I recover ?

I only get 2 tabs ... blank Inbox and 2nd tab to set up email address (pics attached)

Today I went to close Thunderbird using File>Exit. It does not close, and I see the the "Emptied Trash" message. If I go to click on "File" again there is often no dropdown. If I go to close it using the "X" it closes. When I try start it again it will not start. I have to go to the task manager where I find instances of it running, and close them...then it will start. When it is started, I can close it using the X and it starts normally. All extensions are disabled.

Very occasionally Thunderbird will close using File>Exit but will not start normally.

Any ideas?

For some time Thunderbird crashes quite often. One reason seems to be Chinese characters in an email I try to open. But it also crashes on other occasions. Several times a day.

"Enter Password" box no longer comes up when I start up Thunderbird. One account has password saved but the other doesn't so I cannot access emails on this account now as they won't download without either a saved password or (as I usually do) entering a password. This affects my husband also so not just something on my account. This happened around the 20th December. I've searched through Thunderbird settings but I can't find any way of adding a password directly into Password Manager - only edit or delete. So I can't fix the problem we now both have with accessing new emails. So - any suggestions please or is there a fix coming?, kind regards

Thanks.

When Thunderbird updated to 102.6.1 the other day, my address book disappeared. No more personal address book or contact lists. Gone. (My 'Personal Address Book" went from 2,000 names to 24. Yikes!)

Plus, I can't even type people's names into the emails and expect it to populate like before. I have to search for their emails and rewrite it.

Is there a way to fix this? Or to roll the program back to the previous version?

Since I backed my email list up last month, I've made lots of changes. But if I have to, I'll just re-import and try to recreate what I've done. (Reminder to self to back up more often).

Thanks for any help or guidance. PS - I'm on Windows 10.

For many years, my wife and I have each used Thunderbird on our own computers. Several weeks ago, when my wife turned Thunderbird on, a new screen appeared that mentioned account setup and directed her to set up her existing email address. When she did, a home screen appeared that was significantly different than the one she had been using. But more than that, she lost all her saved emails and Thunderbird started to reload emails. The reloading ended with over 1800 “new” emails whose dates reached back for almost a year. Since then, after some work, the home page has been returned to its earlier look; downloading, sending and deleting are working as before. Missing are a few important, personal subfolders. We’ve tried a few things that we thought/hoped would return us to the point before everything went crazy. That hasn’t happened. Recently, we looked at the Profiles folder on each of our computers and saw something that, I think, is unusual and, I hope, might provide a way get her back at least some of what was lost.

The route to my Profiles is C: > Users > Me > AppData > Roaming > Thunderbird > Profiles In Profiles are two folders, one ends with .default and the other with .default-release. The only thing in the default folder is the file times.json. The default-release folder contains many files and folders, including the Mail folder. The Mail folder contains two subfolders: Local Folders and mail.comcast.net.

On my wife’s computer, there is only one folder inside Profiles. The name ends in .default. Inside that folder is the Mail folder. Within the Mail folder are six subfolders: Local Folders, Local Folders-1, Local Folders-2, mail.comcast.net, mail.comcast.net-1, mail.comcast.net-2. The Date Modified date for Local Folders is probably the date the problem started. Date Modified for Local Folders-1, mail.comcast.net and mail.comcast.net-1 is the same: a few days after the date for Local Folders. The dates for Date Modified for Local Folders-2 and mail.comcast.net-2 are the same, and change daily.

I’m hoping/assuming that the missing, personal subfolders are in one, or more, of Local Folders, Local Folders-1, mail.comcast.net, mail.comcast.net-1. What I’m asking here is: does anyone know of a way to easily locate and recover the subfolders and, then, move them into the correct location in Local Folders-2and/or mail.comcast.net-2.

Thanks for taking the time to read this long story.

Earlier this week I notice that my Thunderbird was upgraded to ver 115.3.3. Now sending email using address book LISTS fails to save the email as draft and fails sending the email. I can send the email if i list each person in the LIST in the TO field. However, none of my address book distribution LISTS work. I use the LIST every week, so I know it worked fine with the previous version??? I even tried to create a new list and that failed the same way, so it looks like LISTS do not work in Version 115.3.3??? Is there a way I can go back to the previous version of Thunderbird??

Troubleshooting Steps:

  1) Closed Thunderbird and retried email using a new LIST; FAILED
  2) Reboot PC and retried. FAILED.
  3) Sent email to multiple recipients without using LISTS. PASSED.
  4) Tried creating a new LIST using recipients I know work. FAILED.
  5) Update Histroy:
        Version 115.3.3 Installed 10/21/23
        Version 102.15.1 Installed 09/13/23
        Version 102.15.0 Installed 8/30/23
  6) Last successful email sent using a LIST on : 10/17/23
  7) Retested failure with Version 115.4.1 (64 bit). FAILS

For the past several TB updates my create new mail windows are stuck on my screen. I cannot move them around unless I inch it along corner by corner. It remembers the last position and opens it again there. I used to be able to move around the compose window without a problem. Anyone know what's wrong and how to fix it?

I'm on Mac OS 12.6, TB 102.5.1 (waiting for the Windows 36 bug to be fixed before updating).

Hello, does anyone know what causes this error. I might have done something silly, but now when I try to check incoming e-mails it says "mailnews.pop3.0: Socket state is closed - won't send command." This is shown if I look at the error console. This happens after I enter the password.
