Thunderbird Support Forum

Hello

Yesterday there was update in Thunderbird and went well. But today, Thunderbird suddenly asking for credentials and then it went totally blank as in screenshot. There is nothing at all. But incoming mails are still showing up in windows notification and it can be opened as new tab of Thunderbird. I have been searching the possible cause and solution from forum and internet, but no luck. Can someone please help me about this ?

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

I have over 200 emails that I can find in search and can view a preview type showing of emails, I can right click or take any action aside from clicking to open email. But when I try to open email it seem to open a new page that is blank and shows a page just like regular email listing but the field showing emails in blank. This same blank results also happens when I can see emails in search window but click the link to view in list view. I just need to open an email enough to be able to see what email address the original email was sent to. I also will add I cant seem to find any of the emails found in search in any of the accounts that being used in Thunderbird (accounts listed in left side column) Also these emails are 2 years old and the computer may or may not have had a OS reset during that time but not sure.

Problem: Thunderbird hangs up on Macbook and iMac. It opens to the normal view, but if I try to do anything, I get the beachball of death. I used Mac migration assistant to install from Macbook to iMac. Before the installation, the Macbook Thunderbird worked fine, but after the installation, neither worked. My PC installation works fine, as does Apple Mail on my iOS devices, so it is not a provider problem.

Solutions tried: restarting in troubleshoot mode, restarting iMac, turning off access to Apple Contacts, turning off antivirus (Norton), creating new profile and copying existing mail data into the profile folder, and renaming various files in the profile folder.

Results: None of the solutions I tried provided access to my email. I can open the new profile, but that requires that I reenter all my email account information and copy the emails for each account into the new profile (I use POP). The problem may be with the prefs.js file, since if I rename it, Thunderbird doesn't hang, but would require me to reenter all my account info as if it were a new profile, and all preferences would be lost.

Question: What is the best solution for this problem? Is there anything that would work better than reentering the account info -- e.g., can I make any changes to prefs.js using a text editor or some other utility?

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it.

It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

For a few weeks I have had a new problem on my new Windows 11 Lenovo laptop, and also on my wife's older Dell laptop. We have been using Thunderbird for years without major problems. I loaded the latest version of Thunderbird on my new laptop and it seemed to work ok at first. Now I have a problem with intermittent failure to send normal emails on Thunderbird. My wife has noticed the same problem on her laptop Windows 11. I asked iPrimus support (who are supposed to support Hotkey) but they say it is not their problem but Thunderbird's. We RECEIVE emails ok, and sometimes pressing SEND will work immediately, sometimes on the second press, and sometimes not at all. This generates a message "-- Unable to authenticate Outgoing Server (SMTP), smtp.hotkey.net.au -- Check password and verify authentification method in Account settings/Outgoing server SMTP" We both use Trend virus protection.

Account name: mail.hotkey.net.au Outgoing Server: smtp.hotkey.net.au Server Settings: Server name pop.hotkey.net.au

                             User name is my email address

I normally open messages in tabs under exactly one circumstance: when I right-click on a message and explicitly open it in a tab.

I've found that (until I changed the handling of PDFs to "Save file") any PDFs that opened using Thunderbird's preview function would reopen if I closed and relaunched Thunderbird. This is not desired behavior.

I will also note that if I open Settings, it opens in a tab, rather than a separate window. This is neither expected nor desired (and my natural reaction is to click the close button on the window, closing Thunderbird, because "Settings" is something I expect to be in a window, not a tab. And that, too, reopens if I reopen Thunderbird.

And worst of all, those tabs that shouldn't be reopening at all are reopening in front of the main tab.

There was an extension called "Thunderbird-DontRestoreTabs," that would do exactly what I want, but that was made obsolete when the underlying extension technology was deprecated, so it is of no use in 115.9.0.

Hi, since I use a set of different browsers for different tasks, it would be great if there was an easy way of opening links from within thunderbird emails to your browser of choice. E.g. via right mouse button: Open Link in ... I use that method in other applications frequently.

Kind regards

I have 3 emails with greatmail.com. One email has this problem (the others are fine) When I open any incoming email, I get this warning at the bottom of the page: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity Joan Dailey<jdailey@expresslyyours.com" </p>

Also, having clicked on it to open it, the email appears to be (automatically) a reply from me and none of the links that may be in the email work... it also appears to be in edit mode.

Further, if I go into my expresslyyours account at https://webmail.greatmail.com, I am allowed to click a box and allow the message to present normally. Part of those emails may be coming to e-store@expresslyyours.com... however, it is happening to ALL emails to my EY mailbox. What can I do to fix this? Where to look? By the way, have discussed this with greatmail and they are puzzled.

I recently purchased a new laptop and needed to migrate my old Thunderbird profiles. This is what I did: 1. Backed up profiles from old laptop 2. downloaded and installed latest version of Thunderbird on new laptop 3. coped profiles into \roaming directory 4. tested and successfully received emails and viewed all old emails.

The problem is that the Mail toolbar is nowhere to be found. Also, the calendar is missing. I tried right clicking on empty space and it only showed "menu bar" as an option. Attachment shows nothing in the toolbars option of View dropdown.

I added a CalDav calendar to Thunderbird that is hosted on a Nextcloud instance. While the calendar view looks decent, the tasks view is completely bloated with old, already completed tasks, some even from 2023. I selected "open tasks" or "current tasks" (? German translation) from the menu on the left side. It's not that all of the tasks are misclassified: When I go to completed tasks, there are hundreds of (correctly) completed tasks listed, but still.

Furthermore, the sub tasks of a main task are not grouped. Is this a known limitation or am I missing some configuration?

In general, as of now, the task view is pretty unusable for me. Anything that I can do to help debugging this?

Dear all, I have a couple of calendars on the disk as network calendars (file:///...ics) with offline support, and I just realized that I cannot delete any event. These calendars are not read-only, I can see the option delete, both with right-click on the event and double-click to edit the event, but after pressing delete, the event remains on the calendar. Just pressing the delete button on the keyboard after selecting the event has the same behaviour. If I try shift the events from one calendar to the other, they do appear in the new calendar, but they do not disappear from the old. I have restarted Thunderbird, and also tried this on another computer with the same results. Both szstems are Windows 11, Th underbird 115.10.1 I would be very grateful for any suggestions

How can I set the email message sort to descending date for all folders in all accounts? With many accounts with many folders each, manually changing the sort from ascending to descending is a lot of needless work. A global default is needed, and if there is one, I can't find it.

I have 3 machines with Thunderbird. A while back I noticed that I had duplicate folders for sent mail (Sent & Sent Mail) and for Drafts. (Drafts and Drafts) I did a search and found a discussion from 2019, but nothing more recent. That one kinda lost me. I just got a new machine and installed Thunderbird again. My Gmail account on the new machine shows the same dual folders. Hopefully someone here can detail a solution in steps for a moron like myself.

Dear all, is there an option to have Thunderbird sync network calendars once upon start? I have a couple of large network calendars and repetitive syncing causes performance problems, but on the other hand, if I set sync to Manual, Thurderbird does not sync upon start and shows only the events that had been cached locally (off-line) in the past, but not any events meanwhile added to the network calendar by other clients. Thus, I either have to remember to manually sync once every calendar after each program start, or I have to activet syncing every xx minutes, which causes the programm to periodically freeze for some time (during syncing). Is there any good solution to this? Is there maybe an option in the config editor "sync upon start"? Thank you very much.

Here's the technical details: Win 10 Home 22H2 Build 19045.4291, Mozilla TB Thunderbird Version 78.4.0 Build ID 20201019003438 Distribution ID Update Folder C:\ProgramData\Mozilla\updates\8216C80C92C4E828

This AM I was able to check / get e-mail five (5) or more times. Then clicking 'Get Mail' displays; connecting to mail.duo-county.com After 15-20 seconds connection to server mail.duo-county.com; Timed Out

I know of NO changes to any setting. When our e-mail was set up, we were told to set we were told to use Pop-3. Our ISP, who does NOT use NOR 'know' TB said we should be using IMAP, could NOT help review nor doing anything without risking ALL folders - files-data!

PLEASE help ASAP. Since we can't get - check mail I'm LOST! My spouse's e-mail is wpj@duo-county.com
