For the past several years I have been dealing with Thunderbird occasionally freezing on me, with the window losing focus and the titlebar saying (Not Responding).

It appears to happen when TB is downloading email. If the emails are large (as some are) TB stops everything to deal with it. I have looked for where to change any settings to allow for process threading, since that was the promise of Windows waaaaay back in 1990. Not so, apparently with TB. Even if I'm in a separate window composing an email, it freezes. I wrote about this back in 2018...

I noticed that this only happens when downloading emails from one particular account, which I use for receiving project code error debug reports. The emails are typically around 150k or slightly less. Not so huge that it should take so long to pull down, but the debug info is in many, many nested tables and divs. Is it trying to render them, even though I don't have them open?

In any case, I set that account to no longer collect. Yet, every once in a while, it still collects. Do I need to remove the account from TB altogether? I would like to be able to have this account checked every 15 minutes like my other five email accounts, which don't cause me any heartache, but it's driving me mad, especially when a throng of those emails come in, like 50 at a time, and I am effectively prevented from doing anything in TB for up to five minutes. I suppose I could craft the emails to be smaller (it's my own code that is sending the debug reports) but the info in there is there on purpose.

Is there a setting I can change somewhere to break off the processing for the main window and the compose windows?

I ran into an error on my Windows 11 PC. If I add an attachment via the system menu called up by the right mouse button, the size of the attachment is displayed in terabits and cannot be sent :-)

I use Thunderbird to check the 15 different email accounts that I have to respond to. On the 4th of June it just quit sending or receiving emails. I tried deleting some of my emails but it hasn't helped. Do you think I haven't deleted enough or would there be another reason for it to quit working.

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

All messages that I delete,send ,archive and drafts, simply disappear without a trace.For years this worked well !Tried downloading and reinstalling Thuderbird without success.

I've just started getting error messages that I need to enter my password to send emails. I've tried that but it still keeps saying unable to connect to the server. This has been happening for about two days now. I've tried updating Thunderbird, restarting Thunderbird and restarting my PC. None of this has worked. I made no changes to my system, software or home network. Any help would be appreciated. Thanks, Dave

I have several Comcast.net accounts that I have set up in Thunderbird. About 2-3 times per week, Thunderbird makes me re-enter one or more of my passwords, only for the comcast accounts. It says Authentication Failure, but I have not changed anything on the accounts, including passwords. Entering the same password works - for a while. Any idea how to stop this?

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

Hi I have asked a question about my new email account in outlook. I have set up a new identity with the new email address. I have set up an app in outlook. I can receive emails but cannot send them. Answer have apparently been posted but I can’t see the email thread either. I really need some help here please. Can the answer be emailed to me or at least a link to where the answer is posted on the thread. Thanks

Hello! Since I couldn't find help in the forums, I will create a new question. For about a year now the PC at my work will not open mailto-links correctly. There is no account to select from, the subject has a lock-symbol. The receiver's address is correct though (I replaced it with "address" for the screenshot). This PC is the only one I know with that problem and only with external mailto-links. If I click on an email address inside a mail, it opens it correctly. Thunderbird version 115.11.1 (32-Bit), Win 10

It's pretty impractical, so I am hoping for help. Thank you!

When going from Help on menu to check for updates receive the error message - Failed to check for updates.

Running on Windows 10 with NAV - problem is recent in origin but I can't be exact as it's not my regular PC.

So far I've manually updated Thunderbird from 115.11.1 to 115.11.2 (64bit)by downloading from Mozilla website, rebooted from cold several times, and applied the fix from Norton:" https://community.norton.com/en/forums/auto-update-norton-360-v2449067835-now-causes-security-exception-thunderbird " in case it was related. It appears to be unrelated because on my regular PC the NAV update occurred necessitating the fix to the security exception error but don't have the checking for updates error.

thanks

Suddenly without warning Thunderbird displays a message 'Checking mail server capabilities.......' in the bottom left of the inbox screen. Messages from the server [Optus] are not downloaded. I have changed the SMTP server to the default 465 and changed the security setting to 'None' but the problem has not been resolved. I note that there are alot of queries about this problem but I cann ot find a solution anywhere on the Mozilla help pages.

Hi. I was receiving emails until 10:30am yesterday and then nothing. No emails are being received on any of my email addresses since then on my Thunderbird site. I can receive them on my phone, so I know I am being sent emails but nothing on my computer. When I click "Get Message", nothing happens. When I try to send a email - "Add Security Exception" screen comes up saying you are about to override how Thunderbird identifies this site. Why has this just started and what do I need to do to be able to receive and send emails again?

I have tried multiple times to add an email account to thunderbird in windows but I keep getting the error, "Unable to log in at server...". I know the details are correct as I'm copying and pasting them from my password manager so I'm not sure what the problem is.

Hi, last week my Thunderbird started slowing down and then appeared an error which caused it to freeze (i wasn't there so i don't know what error). The program was force closed and opened again, and it started re-downloading messages in the inbox (probably repairing).

For some reason it also started running all the filters and sent a ton of old emails from the inbox. I closed it again and after opening it it worked fine, and it continued downloading messages during the weekend. Today it worked fine all day until it started running the filters again. I closed it and opened it again and it continued sending emails, so i had to close it.

I'm not sure but it may have happened after making a new filter, which is strange because i have about 180 filters and this never happened before.

I'm now afraid of opening thunderbird because it may continue sending emails.

Could this be a thunderbird bug or an add-on issue? I have Send Later as well as FiltaQuilla, which i disabled the last time i opened thunderbird.

I have Thunderbird 115.11.1 running on a Mac Mini M2 Sonoma 14.5.

I use a Kensington USB PC Keyboard which is set to "British-PC" in the Mac Keyboard settings to give the correct layout.

If Thunderbird is the first app I launch after I log in (the password entry at this stage works fine) it seems to stop the keyboard from being recognised by the Mac until I go into another app (Google or Text Edit for instance) which then seems to make the Keyboard visible again.

Are there any settings in Thunderbird that might clash with the system keyboard settings and cause this?

If I use other apps before launching Thunderbird it works as normal, it seems to happen if Thunderbird is launched first.

Thanks for any help.

Using TB 115.11.0 (32-bit) on a Windows 10 machine, with IMAP synchronization. Quite often (but not always) the synchronization of the inbox takes an extremely long time, Activity Manager showing "bringing folder inbox up to date" hanging in "downloading message 1 of ...".

I have made a Gecko IMAP:5 log and see (during this state) a pattern repeating every 2 minutes, ending in "idle mode async waiting". Then, after a long time suddenly the synchronization process finishes.

What can be wrong here?

I have had the same filters and folders for years. Now pretty much everything is not filtered when messages arrive, and when I do a manual "Run Filters on Folder" I get this message about many, maybe all, of my filters "The folder 'Newsletters' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder."

"Applying filter From is: dailybusinessreview@alm.com failed. Would you like to continue applying filters?"

When I try redoing the filter, filter dialog says it can't find the folder. I tried repairing the folder, no good.

Junk filters after years of learning, aren't working either.

Now what? TIA.
