Please let me know if it is safe to remove the older version of Thunderbird in the Installed Apps list. I also question whether the size of the app in the list is accurate; 250 GB seems quite enormous in a 500 GB hard drive. Thanks, Hans

Delay moving messages to and from 4 certain mailboxes (win10, v152)

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

Windooze 11. TBird 152.0 installed on June 20th. Now it seems like TBird is not displaying HTML emails properly. They are displayed but not at the beginning. The first line is sometimes just the bottom half of a sentence in the email (if that makes sense). I can't scroll back to the beginning. If I go to outlook and display the same email it displays fine.

Did something change in 152.0 to cause this?

Thanks, Ed Mazurek

When an email that is part of a thread is selected the delete button changes places with archive so I end up with a bunch of archives I don't want because I get a lot of mail and delete is my favorite key to spam.

Is there a way of changing this placement behavior or do I need to hack the source and if I do need to go hacking can someone point me in the direction of the file with this evil thing.

At some point recently, Thunderbird started ignoring the page range I specify in the print dialog box. I regularly have documents that are 4-5 pages, however I only need the first page printed. So in the print dialog, I set it to double sided printing, and to print only pages 1-2. In the past, it would only print a single (double sided) page...recently, it started printing all of the pages, and ignoring the setting I provided. Any help would be appreciated!

Good morning,

I’m reaching out because I’m having trouble with my Thunderbird email and need some assistance.

I was using Thunderbird without any issues before, but now all my old emails have disappeared. I can still receive new messages, but I’m unable to send emails like I used to. I also can’t recover or view any of my previous emails.

It seems like something may have reset or become corrupted, and I’m not sure how to restore my old messages or fix the sending issue.

Could you please help me get Thunderbird working properly again and recover my old emails if possible?

Thank you for your support.

I've had a Thunderbird email account for years. My laptop quit, so I've set up the account on a new laptop. I discovered that I hadn't saved my Thunderbird password, so I followed the procedure for "forgot password". This included a new p/w, and I also got a Mozilla PIN (for future Microsoft Password Manager use), and got a Mozilla Account Recovery Key, again for future use. But I can't log into my Thunderbird account. I get the message "Authentication Error" (Wrong p/w, email, etc.) Changing IMAP / POP settings didn't help, though I did go with the recommended IMAP setting.

Any suggestions?

Hello,

I'm currently using the thunderbird client to open a zoho mail account. I've set several filters (around 40) so that incoming emails are automatically redirected to the appropiate folder. If I click on the download/refresh icon (the little cloud with the downwards arrow), new email isn't received. On the bottom, a small message appears ("No new messages on the server" or something like this). You may think that that is precisely because I don't have new emails but if directly go into any of the folders and once again click on the download/refresh icon all of the emails that were supposed to go into that particular folder appear all at once (even mails that are 2 or 3 days old). Now every day I have to go into all of my 40 folders and click on the refresh button.

I look forward to your help. Kind Regards.

Hello all,

Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.

Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk

The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.

The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.

The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.

Messages in all of the other folders are visible.

At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).

I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).

I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.

Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.

I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.

Thanks in advance.

As of a few weeks ago, none of the links on the Add-ons Manager Details pages in my TB 152 work, e.g. Author or Homepage. Moving the mouse over them, left-clicking on them, right-clicking on them, no effect at all. Which is annoying, as with several add-ons I use I'll want to go the add-on's Github page to look for new betas, report issues etc. Those links all used to work, opening the linked page as a tab in Thunderbird, but now they don't work at all, not even a right-click menu option to open in browser. Still not working in 152.0.1. This isn't only with me, surely?
