Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

Hi! I'm trying to set Thunderbird as the operating system default under Win 11. I tried to follow Mozilla's instructions: 1. Open the Settings application by pressing and releasing the Windows Start button, then clicking the gear icon. 2. Click the Apps icon, then click Default Apps in the list. 3. Click the icon under the heading Email to show your choices. 4. Select Thunderbird. The trouble is that at n. 3 there is no choice. There is only 'OutlookAccounts' and this item cannot be deleted or replaced. Can you help? All the best, Robifiori

Hello,

Recently I have started to have emails fail to deliver to a certain domain and the message that comes back is

550 DKIM Sender Invalid - envelope rejected.

I am using Thunderbird v128.8.1 esr (64-bit). Extensions installed are: 1. Attachment Saver (Deimios, v.0.2.2) 2. FileLink provider for Send (Teal Dulcet v2.1.1) 3. Remove Duplicate Messages (Eyal Rozenberg v0.6.1)

I have been in communication with this client for several years and not had this problem before. When I send email to the same recipients using WebMail there is no problem, it is only when I send from Thunderbird.

I am not using any encryption type of setup.

Has anyone come across this before? Does anyone know of a solution?

Thanks, Franc.

I have no idea why, but TB is wonking out lately with strange errors?

The folder '[Gmail]/Sent Mail on me@mydomain.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I have a ton of space and have not changed anything on the PC?

Any ideas?

Can I use Thunderbird to build an incremental local backup/archive of all messages transiting (incoming/outgoing) a webmail account ?

Any idea how to achieve this ?

My problem is:

  • A POP3 account will miss all folders except the Inbox. (It's a pity that POP4 has not gained traction yet.)
  • An IMAP account creates a mirror, not a backup. Remote deletions in the webmail account must not delete messages from my backup and vice versa.

detailed requirements:

  • one-way sync only, since a local backup/archive must be built, not a mirror (two-way synchronization):
    • Remote deletions must not cause local deletions (otherwise it would be a mirror, not an archive/backup).
    • Local move/delete operations must not be reflected back to the mail server.
    • Read‐only access to the mail server: no moves, deletes or flags remotely.
  • All messages in all folders must be included in the backup: Inbox, Sent, custom folders, etc. Since POP3 can only back up the Inbox, I will probably have to settle for IMAP to include all folders.
  • No duplicates: Messages must not be stored locally more than once.
  • Messages must be stored as full offline copies locally (not just headers).

Yes, please don't give me the MS ctrl-alt-del type of response about cookies.... That was done many times before posting this. The website works fine in Brave. MS Edge well, let's not speak of it in public company shall we.

So, now what the heck is happening to FF???? I have contacted HF three times and they referred me to use other browsers other than FF. No, I DO NOT have multiple extensions nor themes. FF is bare bones but for uBlock. Hardware acceleration is off and MS Clear type is on. Anybody wanna fess up, who broke this????

Outlook email address shows up as jumbled mess in Thunderbird - Sending and receiving addresses are also swapped

I have two issues that are related to a buggy interaction between Thunderbird and Microsoft's email server. Issue (1) When I send an email with my Outlook email address … (funda kabanzi)

I have two issues that are related to a buggy interaction between Thunderbird and Microsoft's email server.

Issue (1) When I send an email with my Outlook email address (from the Android app or from outlook.live.com, but not Thunderbird), my email address shows up as a jumbled mess in the sent folder on Thunderbird.

It appears to the effect of

IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+XXXXXXXXXXXXXXXXX+29_CN=RECIPIENTS_CN=XXXXXXXXXXXXXXXX@sct-XX-XX-XXXX-X-msonline-outlook-6f06c.templateTenant

(I have masked some potentially sensitive information).

In the sent folder on my Outlook Android app, my email address looks normal. It also looks fine on a browser in outlook.live.com. However, it's in the sent folder on Thunderbird that my email address is a mess.

Issue (2) When my Outlook email address is involved, the sending and receiving email addresses in the "correspondent" field are swapped in Thunderbird.

There are a couple situations where this swap happens:

  1. Sending an email with my Outlook email account (either through the Android app or outlook.live.com, but not Thunderbird). In my Outlook sent folder on Thunderbird, the "correspondent" field shows my jumbled email address and not the receiving address, such as bob@gmail.com. Likewise, In the inbox of the receiving email account (such as bob@gmail.com) on Thunderbird, the "correspondent" field shows bob@gmail.com and not my Outlook email address.
  2. Sending an email with any other account in Thunderbird to my Outlook email address. In my Outlook inbox on Thunderbird, the "correspondent" field shows my Outlook email address (this time unjumbled) and not the sending email address. However, in the sent folder of the sending email account in Thunderbird, the "correspondent" field shows up correctly (i.e., my Outlook email address).

These two issues are perplexing and probably related. Thank you for any help!

Owing to a price rise in MS Office, I had been looking to move to free software. Unfortunately for email this isn't working. I have downloaded Thunderbird and have tried to transfer my Outlook data there. I started two weeks ago and on average believe the process has been running a few hours a day, for much of the time when I look occupying 0% of CPU capacity, and most of the time not rising above 1%. The import has been stuck at 33% for that time, which I assume means that it imported Accounts and Settings or Address Books quickly and is taking a very long time to import Mail Messages. (It imported the couple of month's worth on webmail quite quickly.) Likely this is owing to the size of the Outlook file, 5 GB. Does this essentially make the transfer impossible? For how large a file could Thunderbird do a successful import?

Sending this using Safari because Firefox is totally messed up. Firefox 115.24.0esr (64-bit) OSX 10.13.6 High Sierra 2011 Mac Power Book (MPB) with 16 GB RAM. Verizon DSL line, download speed tests from 10-14 Gb/sec but Latency is always 400-900+ msec. No way to measure Jitter with speedtests that will run on my older system, or Bufferbloat now that DSLreports has gone dark.

I want a tool that will allow me to see all the attempts to connect, and packets/traffic, to see it its my old computer going bad, Firefox, the wireless or wired connection to the DSL modem/router, or the DLS modem/router itself, such as a problem with reaching the Domain Name Server (DNS) etc.

I can access the DSL modem/router in the browser, but there isn't much documentation. Its made by Actiontec but customized firmware for Verizon.

The problem persists whether I am using wifi or an Ethernet cable.

My wifes 2010 MBP computer with 8GB RAM using about 6.4GB, running High Sierra and Firefox 115.24.0 (esr) seems not to have the problem at all.

Firefox will show something in the lower left corner, "connecting to..." or "loading..." etc. It can stall with either status.

Search engines would be StartPage or DuckDuckgo. With DDgo, sometimes it just spins forever, but if I click on the URL bar, it drops down another line with the same URL and "--Visit" appended. Sometimes that will load, but seems random.

Some URLs / links open in a few seconds, some spin forever.

I first called Verizon Tech support on May22 about problems (see full exchange of repeated calls & new trouble tickets below). I think, IIRC, this happens to be shortly after I upgraded my Firefox version. They have admitted to PINGs not returning, packet loss, no excuse for the Latency.

I do have a lot of pages/tabs open; Activity Monitor says my memory use is about 14GB, but the Memory Pressure stays low in the green. I also run Thunderbird, TextEdit, maybe Adobe Reader and Excel. But even when I close everything else, the non-loading issue persists. When I shut down Firefox, the memory pressure can go into the red and take a very long time (so I always shut down all other apps first). A recent shutdown stalled & I ended up losing many open pages/tabs, but even the slimmed down load has the same problem.

I have shut off the AddOn NoScript, but the problem persists.
